Clock precision differences between time.Now() calls - System timing variations and NTP corrections - Microsecond vs nanosecond precision differences ✅ **CURRENT_DATE test**: Enhanced to handle midnight boundary crossings: - Captures date before and after function call - Accepts either date value in case of midnight transition - Prevents false failures during overnight test runs **Testing:** - Verified with repeated test runs (5x iterations) - all pass consistently - Full test suite passes - no regressions introduced - Tests are now robust against timing edge cases **Impact:** 🚀 **Eliminated flaky test failures** while maintaining function correctness validation 🔧 **Production-ready testing** that works across different system environments ⚡ **CI/CD reliability** -

Short: "start a PostgreSQL-compatible database server for SQL queries",
|
||||
Long: `Start a PostgreSQL wire protocol compatible database server that provides SQL query access to SeaweedFS.
|
||||
|
||||
This database server enables any PostgreSQL client, tool, or application to connect to SeaweedFS
|
||||
and execute SQL queries against MQ topics. It implements the PostgreSQL wire protocol for maximum
|
||||
compatibility with the existing PostgreSQL ecosystem.
|
||||
|
||||
Examples:
|
||||
|
||||
# Start database server on default port 5432
|
||||
weed db
|
||||
|
||||

|
||||
weed db -auth=md5 -users='{"admin":"secret","readonly":"view123"}'
|
||||
|
||||
# Start with complex passwords using JSON format
|
||||
weed db -auth=md5 -users='{"admin":"pass;with;semicolons","user":"password:with:colons"}'
|
||||
|
||||
# Start with credentials from JSON file (most secure)
|
||||
weed db -auth=md5 -users="@/etc/seaweedfs/users.json"
|
||||
|
||||
# Start with custom port and master
|

||||
- JSON format: '{"user1":"pass1","user2":"pass2"}' (supports any special characters)
|
||||
- File format: "@/path/to/users.json" (JSON file)
|
||||
|
||||
Note: JSON format supports passwords with semicolons, colons, and any other special characters.
|
||||
File format is recommended for production to keep credentials secure.
|
||||
|
||||
Compatible Tools:
|
||||
- psql (PostgreSQL command line client)
|
||||
- Any PostgreSQL JDBC/ODBC compatible tool
|
||||
|
||||
Security Features:
|
||||
- Multiple authentication methods
|
||||
- TLS encryption support
|
||||
- Read-only access (no data modification)
|
||||
|
||||
Performance Features:
|
||||
- Fast path aggregation optimization (COUNT, MIN, MAX without WHERE clauses)
|
||||
- Hybrid data scanning (parquet files + live logs)
|
||||
- PostgreSQL wire protocol
|
||||
- Query result streaming

# PostgreSQL Wire Protocol Support for SeaweedFS
|
||||
|
||||
## Overview
|
||||
|
||||
This design adds native PostgreSQL wire protocol support to SeaweedFS, enabling compatibility with all PostgreSQL clients, tools, and drivers without requiring custom implementations.
|
||||
|
||||
## Benefits
|
||||
|
||||
### Universal Compatibility
|
||||
- **Standard PostgreSQL Clients**: psql, pgAdmin, Adminer, etc.
|
||||
- **JDBC/ODBC Drivers**: Use standard PostgreSQL drivers
|
||||
- **BI Tools**: Tableau, Power BI, Grafana, Superset with native PostgreSQL connectors
|
||||
- **ORMs**: Hibernate, ActiveRecord, Django ORM, etc.
|
||||
- **Programming Languages**: Native PostgreSQL libraries in Python (psycopg2), Node.js (pg), Go (lib/pq), etc.
|
||||
|
||||
### Enterprise Integration
|
||||
- **Existing Infrastructure**: Drop-in replacement for PostgreSQL in read-only scenarios
|
||||
- **Migration Path**: Easy transition from PostgreSQL-based analytics
|
||||
- **Tool Ecosystem**: Leverage entire PostgreSQL ecosystem
|
||||
|
||||
## Architecture
|
||||
|
||||
```

└──────────────────┘
|
||||
```
|
||||
|
||||
## Core Components
|
||||
|
||||
### 1. PostgreSQL Wire Protocol Handler
|
||||
|
||||
```go
|
||||
// PostgreSQL message types
|
||||
const (
|
||||
PG_MSG_STARTUP = 0x00 // Startup message
|
||||
PG_MSG_QUERY = 'Q' // Simple query
|
||||
PG_MSG_PARSE = 'P' // Parse (prepared statement)
|
||||
PG_MSG_BIND = 'B' // Bind parameters
|
||||
PG_MSG_EXECUTE = 'E' // Execute prepared statement
|
||||
PG_MSG_DESCRIBE = 'D' // Describe statement/portal
|
||||
PG_MSG_CLOSE = 'C' // Close statement/portal
|
||||
PG_MSG_FLUSH = 'H' // Flush
|
||||
PG_MSG_SYNC = 'S' // Sync
|
||||
PG_MSG_TERMINATE = 'X' // Terminate connection
|
||||
PG_MSG_PASSWORD = 'p' // Password message
|
||||
)
|
||||
|
||||
// PostgreSQL response types
|
||||
const (
|
||||
PG_RESP_AUTH_OK = 'R' // Authentication OK
|
||||
PG_RESP_AUTH_REQ = 'R' // Authentication request
|
||||
PG_RESP_BACKEND_KEY = 'K' // Backend key data
|
||||
PG_RESP_PARAMETER = 'S' // Parameter status
|
||||
PG_RESP_READY = 'Z' // Ready for query
|
||||
PG_RESP_COMMAND = 'C' // Command complete
|
||||
PG_RESP_DATA_ROW = 'D' // Data row
|
||||
PG_RESP_ROW_DESC = 'T' // Row description
|
||||
PG_RESP_PARSE_COMPLETE = '1' // Parse complete
|
||||
PG_RESP_BIND_COMPLETE = '2' // Bind complete
|
||||
PG_RESP_CLOSE_COMPLETE = '3' // Close complete
|
||||
PG_RESP_ERROR = 'E' // Error response
|
||||
PG_RESP_NOTICE = 'N' // Notice response
|
||||
)
|
||||
```
|
||||
|
||||
### 2. Session Management
|
||||
|
||||
```go
|
||||
type PostgreSQLSession struct {
|
||||
conn net.Conn
|
||||
reader *bufio.Reader
|
||||
writer *bufio.Writer
|
||||
authenticated bool
|
||||
username string
|
||||
database string
|
||||
parameters map[string]string
|
||||
preparedStmts map[string]*PreparedStatement
|
||||
portals map[string]*Portal
|
||||
transactionState TransactionState
|
||||
processID uint32
|
||||
secretKey uint32
|
||||
}
|
||||
|
||||
type PreparedStatement struct {
|
||||
name string
|
||||
query string
|
||||
paramTypes []uint32
|
||||
fields []FieldDescription
|
||||
}
|
||||
|
||||
type Portal struct {
|
||||
name string
|
||||
statement string
|
||||
parameters [][]byte
|
||||
suspended bool
|
||||
}
|
||||
```
|
||||
|
||||
### 3. SQL Translation Layer
|
||||
|
||||
```go
|
||||
type PostgreSQLTranslator struct {
|
||||
dialectMap map[string]string
|
||||
}
|
||||
|
||||
// Translates PostgreSQL-specific SQL to SeaweedFS SQL
|
||||
func (t *PostgreSQLTranslator) TranslateQuery(pgSQL string) (string, error) {
|
||||
// Handle PostgreSQL-specific syntax:
|
||||
// - SELECT version() -> SELECT 'SeaweedFS 1.0'
|
||||
// - SELECT current_database() -> SELECT 'default'
|
||||
// - SELECT current_user -> SELECT 'seaweedfs'
|
||||
// - \d commands -> SHOW TABLES/DESCRIBE equivalents
|
||||
// - PostgreSQL system catalogs -> SeaweedFS equivalents
|
||||
}
|
||||
```
|
||||
|
||||
### 4. Data Type Mapping
|
||||
|
||||
```go
|
||||
var PostgreSQLTypeMap = map[string]uint32{
|
||||
"TEXT": 25, // PostgreSQL TEXT type
|
||||
"VARCHAR": 1043, // PostgreSQL VARCHAR type
|
||||
"INTEGER": 23, // PostgreSQL INTEGER type
|
||||
"BIGINT": 20, // PostgreSQL BIGINT type
|
||||
"FLOAT": 701, // PostgreSQL FLOAT8 type
|
||||
"BOOLEAN": 16, // PostgreSQL BOOLEAN type
|
||||
"TIMESTAMP": 1114, // PostgreSQL TIMESTAMP type
|
||||
"JSON": 114, // PostgreSQL JSON type
|
||||
}
|
||||
|
||||
func SeaweedToPostgreSQLType(seaweedType string) uint32 {
|
||||
if pgType, exists := PostgreSQLTypeMap[strings.ToUpper(seaweedType)]; exists {
|
||||
return pgType
|
||||
}
|
||||
return 25 // Default to TEXT
|
||||
}
|
||||
```
|
||||
|
||||
## Protocol Implementation
|
||||
|
||||
### 1. Connection Flow
|
||||
|
||||
```
|
||||
Client Server
|
||||
│ │
|
||||
├─ StartupMessage ────────────►│
|
||||
│ ├─ AuthenticationOk
|
||||
│ ├─ ParameterStatus (multiple)
|
||||
│ ├─ BackendKeyData
|
||||
│ └─ ReadyForQuery
|
||||
│ │
|
||||
├─ Query('SELECT 1') ─────────►│
|
||||
│ ├─ RowDescription
|
||||
│ ├─ DataRow
|
||||
│ ├─ CommandComplete
|
||||
│ └─ ReadyForQuery
|
||||
│ │
|
||||
├─ Parse('stmt1', 'SELECT $1')►│
|
||||
│ └─ ParseComplete
|
||||
├─ Bind('portal1', 'stmt1')───►│
|
||||
│ └─ BindComplete
|
||||
├─ Execute('portal1')─────────►│
|
||||
│ ├─ DataRow (multiple)
|
||||
│ └─ CommandComplete
|
||||
├─ Sync ──────────────────────►│
|
||||
│ └─ ReadyForQuery
|
||||
│ │
|
||||
├─ Terminate ─────────────────►│
|
||||
│ └─ [Connection closed]
|
||||
```
|
||||
|
||||
### 2. Authentication
|
||||
|
||||
```go
|
||||
type AuthMethod int
|
||||
|
||||
const (
|
||||
AuthTrust AuthMethod = iota
|
||||
AuthPassword
|
||||
AuthMD5
|
||||
AuthSASL
|
||||
)
|
||||
|
||||
func (s *PostgreSQLServer) handleAuthentication(session *PostgreSQLSession) error {
|
||||
switch s.authMethod {
|
||||
case AuthTrust:
|
||||
return s.sendAuthenticationOk(session)
|
||||
case AuthPassword:
|
||||
return s.handlePasswordAuth(session)
|
||||
case AuthMD5:
|
||||
return s.handleMD5Auth(session)
|
||||
default:
|
||||
return fmt.Errorf("unsupported auth method")
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### 3. Query Processing
|
||||
|
||||
```go
|
||||
func (s *PostgreSQLServer) handleSimpleQuery(session *PostgreSQLSession, query string) error {
|
||||
// 1. Translate PostgreSQL SQL to SeaweedFS SQL
|
||||
translatedQuery, err := s.translator.TranslateQuery(query)
|
||||
if err != nil {
|
||||
return s.sendError(session, err)
|
||||
}
|
||||
|
||||
// 2. Execute using existing SQL engine
|
||||
result, err := s.sqlEngine.ExecuteSQL(context.Background(), translatedQuery)
|
||||
if err != nil {
|
||||
return s.sendError(session, err)
|
||||
}
|
||||
|
||||
// 3. Send results in PostgreSQL format
|
||||
err = s.sendRowDescription(session, result.Columns)
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
|
||||
for _, row := range result.Rows {
|
||||
err = s.sendDataRow(session, row)
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
}
|
||||
|
||||
return s.sendCommandComplete(session, fmt.Sprintf("SELECT %d", len(result.Rows)))
|
||||
}
|
||||
```
|
||||
|
||||
## System Catalogs Support
|
||||
|
||||
PostgreSQL clients expect certain system catalogs. We'll implement views for key ones:
|
||||
|
||||
```sql
|
||||
-- pg_tables equivalent
|
||||
SELECT
|
||||
'default' as schemaname,
|
||||
table_name as tablename,
|
||||
'seaweedfs' as tableowner,
|
||||
NULL as tablespace,
|
||||
false as hasindexes,
|
||||
false as hasrules,
|
||||
false as hastriggers
|
||||
FROM information_schema.tables;
|
||||
|
||||
-- pg_database equivalent
|
||||
SELECT
|
||||
database_name as datname,
|
||||
'seaweedfs' as datdba,
|
||||
'UTF8' as encoding,
|
||||
'C' as datcollate,
|
||||
'C' as datctype
|
||||
FROM information_schema.schemata;
|
||||
|
||||
-- pg_version equivalent
|
||||
SELECT 'SeaweedFS 1.0 (PostgreSQL 14.0 compatible)' as version;
|
||||
```
|
||||
|
||||
## Configuration
|
||||
|
||||
### Server Configuration
|
||||
```go
|
||||
type PostgreSQLServerConfig struct {
|
||||
Host string
|
||||
Port int
|
||||
Database string
|
||||
AuthMethod AuthMethod
|
||||
Users map[string]string // username -> password
|
||||
TLSConfig *tls.Config
|
||||
MaxConns int
|
||||
IdleTimeout time.Duration
|
||||
}
|
||||
```
|
||||
|
||||
### Client Connection String
|
||||
```bash
|
||||
# Standard PostgreSQL connection strings work
|
||||
psql "host=localhost port=5432 dbname=default user=seaweedfs"
|
||||
PGPASSWORD=secret psql -h localhost -p 5432 -U seaweedfs -d default
|
||||
|
||||
# JDBC URL
|
||||
jdbc:postgresql://localhost:5432/default?user=seaweedfs&password=secret
|
||||
```
|
||||
|
||||
## Command Line Interface
|
||||
|
||||
```bash
|
||||
# Start PostgreSQL protocol server
|
||||
weed db -port=5432 -auth=trust
|
||||
weed db -port=5432 -auth=password -users="admin:secret;readonly:pass"
|
||||
weed db -port=5432 -tls-cert=server.crt -tls-key=server.key
|
||||
|
||||
# Configuration options
|
||||
-host=localhost # Listen host
|
||||
-port=5432 # PostgreSQL standard port
|
||||
-auth=trust|password|md5 # Authentication method
|
||||
-users=user:pass;user2:pass2 # User credentials (password/md5 auth) - use semicolons to separate users
|
||||
-database=default # Default database name
|
||||
-max-connections=100 # Maximum concurrent connections
|
||||
-idle-timeout=1h # Connection idle timeout
|
||||
-tls-cert="" # TLS certificate file
|
||||
-tls-key="" # TLS private key file
|
||||
```
|
||||
|
||||
## Client Compatibility Testing
|
||||
|
||||
### Essential Clients
|
||||
- **psql**: PostgreSQL command line client
|
||||
- **pgAdmin**: Web-based administration tool
|
||||
- **DBeaver**: Universal database tool
|
||||
- **DataGrip**: JetBrains database IDE
|
||||
|
||||
### Programming Language Drivers
|
||||
- **Python**: psycopg2, asyncpg
|
||||
- **Java**: PostgreSQL JDBC driver
|
||||
- **Node.js**: pg, node-postgres
|
||||
- **Go**: lib/pq, pgx
|
||||
- **.NET**: Npgsql
|
||||
|
||||
### BI Tools
|
||||
- **Grafana**: PostgreSQL data source
|
||||
- **Superset**: PostgreSQL connector
|
||||
- **Tableau**: PostgreSQL native connector
|
||||
- **Power BI**: PostgreSQL connector
|
||||
|
||||
## Implementation Plan
|
||||
|
||||
1. **Phase 1**: Basic wire protocol and simple queries
|
||||
2. **Phase 2**: Extended query protocol (prepared statements)
|
||||
3. **Phase 3**: System catalog views
|
||||
4. **Phase 4**: Advanced features (transactions, notifications)
|
||||
5. **Phase 5**: Performance optimization and caching
|
||||
|
||||
## Limitations
|
||||
|
||||
### Read-Only Access
|
||||
- INSERT/UPDATE/DELETE operations not supported
|
||||
- Returns appropriate error messages for write operations
|
||||
|
||||
### Partial SQL Compatibility
|
||||
- Subset of PostgreSQL SQL features
|
||||
- SeaweedFS-specific limitations apply
|
||||
|
||||
### System Features
|
||||
- No stored procedures/functions
|
||||
- No triggers or constraints
|
||||
- No user-defined types
|
||||
- Limited transaction support (mostly no-op)
|
||||
|
||||
## Security Considerations
|
||||
|
||||
### Authentication
|
||||
- Support for trust, password, and MD5 authentication
|
||||
- TLS encryption support
|
||||
- User access control
|
||||
|
||||
### SQL Injection Prevention
|
||||
- Prepared statements with parameter binding
|
||||
- Input validation and sanitization
|
||||
- Query complexity limits
|
||||
|
||||
## Performance Optimizations
|
||||
|
||||
### Connection Pooling
|
||||
- Configurable maximum connections
|
||||
- Connection reuse and idle timeout
|
||||
- Memory efficient session management
|
||||
|
||||
### Query Caching
|
||||
- Prepared statement caching
|
||||
- Result set caching for repeated queries
|
||||
- Metadata caching
|
||||
|
||||
### Protocol Efficiency
|
||||
- Binary result format support
|
||||
- Batch query processing
|
||||
- Streaming large result sets
|
||||
|
||||
This design provides a comprehensive PostgreSQL wire protocol implementation that makes SeaweedFS accessible to the entire PostgreSQL ecosystem while maintaining compatibility and performance.

- **Wire Protocol Implementation**: Full PostgreSQL 3.0 protocol support
|
||||
- **Message Handlers**: Startup, query, parse/bind/execute sequences
|
||||
- **Response Generation**: Row descriptions, data rows, command completion
|
||||
- **Data Type Mapping**: SeaweedFS to PostgreSQL type conversion
|
||||
- **SQL Parser**: Uses PostgreSQL-native parser for full dialect compatibility
|
||||
- **Error Handling**: PostgreSQL-compliant error responses
|
||||
- **MQ Integration**: Direct integration with SeaweedFS SQL engine for real topic data
|
||||
- **System Query Support**: Essential PostgreSQL system queries (version, current_user, etc.)
|
||||
- **Database Context**: Session-based database switching with USE commands
|
||||
|
||||
## Key Features
|
||||
|
||||
### Real MQ Topic Integration
|
||||
The PostgreSQL server now directly integrates with SeaweedFS Message Queue topics, providing:
|
||||
|
||||
- **Live Topic Discovery**: Automatically discovers MQ namespaces and topics from the filer
|
||||
- **Real Schema Information**: Reads actual topic schemas from broker configuration
|
||||
- **Actual Data Access**: Queries real MQ data stored in Parquet and log files
|
||||
- **Dynamic Updates**: Reflects topic additions and schema changes automatically
|
||||
- **Consistent SQL Engine**: Uses the same SQL engine as `weed sql` command
|
||||
|
||||
### Database Context Management
|
||||
- **Session Isolation**: Each PostgreSQL connection has its own database context
|
||||
- **USE Command Support**: Switch between namespaces using standard `USE database` syntax
|
||||
- **Auto-Discovery**: Topics are discovered and registered on first access
|
||||
- **Schema Caching**: Efficient caching of topic schemas and metadata
|
||||
|
||||
## Usage
|
||||
|
||||
### Import the Package
|
||||
```go
|
||||
import "github.com/seaweedfs/seaweedfs/weed/server/postgres"
|
||||
```
|
||||
|
||||
### Create and Start Server
|
||||
```go
|
||||
config := &postgres.PostgreSQLServerConfig{
|
||||
Host: "localhost",
|
||||
Port: 5432,
|
||||
AuthMethod: postgres.AuthMD5,
|
||||
Users: map[string]string{"admin": "secret"},
|
||||
Database: "default",
|
||||
MaxConns: 100,
|
||||
IdleTimeout: time.Hour,
|
||||
}
|
||||
|
||||
server, err := postgres.NewPostgreSQLServer(config, "localhost:9333")
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
|
||||
err = server.Start()
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
|
||||
// Server is now accepting PostgreSQL connections
|
||||
```
|
||||
|
||||
## Authentication Methods
|
||||
|
||||
The package supports three authentication methods:
|
||||
|
||||
### Trust Authentication
|
||||
```go
|
||||
AuthMethod: postgres.AuthTrust
|
||||
```
|
||||
- No password required
|
||||
- Suitable for development/testing
|
||||
- Not recommended for production
|
||||
|
||||
### Password Authentication
|
||||
```go
|
||||
AuthMethod: postgres.AuthPassword,
|
||||
Users: map[string]string{"user": "password"}
|
||||
```
|
||||
- Clear text password transmission
|
||||
- Simple but less secure
|
||||
- Requires TLS for production use
|
||||
|
||||
### MD5 Authentication
|
||||
```go
|
||||
AuthMethod: postgres.AuthMD5,
|
||||
Users: map[string]string{"user": "password"}
|
||||
```
|
||||
- Secure hashed authentication with salt
|
||||
- **Recommended for production**
|
||||
- Compatible with all PostgreSQL clients
|
||||
|
||||
## TLS Configuration
|
||||
|
||||
Enable TLS encryption for secure connections:
|
||||
|
||||
```go
|
||||
cert, err := tls.LoadX509KeyPair("server.crt", "server.key")
|
||||
if err != nil {
|
||||
return err
|
||||
}
|
||||
|
||||
config.TLSConfig = &tls.Config{
|
||||
Certificates: []tls.Certificate{cert},
|
||||
}
|
||||
```
|
||||
|
||||

## Architecture Notes
|
||||
|
||||
### SQL Parser Dialect Considerations
|
||||
|
||||
**✅ POSTGRESQL ONLY**: SeaweedFS SQL engine exclusively supports PostgreSQL syntax:
|
||||
|
||||
- **✅ Core Engine**: `engine.go` uses custom PostgreSQL parser for proper dialect support
|
||||
- **PostgreSQL Server**: Uses PostgreSQL parser for optimal wire protocol compatibility
|
||||
- **Parser**: Custom lightweight PostgreSQL parser for full PostgreSQL compatibility
|
||||
- **Support Status**: Only PostgreSQL syntax is supported - MySQL parsing has been removed
|
||||
|
||||
**Key Benefits of PostgreSQL Parser**:
|
||||
- **Native Dialect Support**: Correctly handles PostgreSQL-specific syntax and semantics
|
||||
- **System Catalog Compatibility**: Supports `pg_catalog`, `information_schema` queries
|
||||
- **Operator Compatibility**: Handles `||` string concatenation, PostgreSQL-specific operators
|
||||
- **Type System Alignment**: Better PostgreSQL type inference and coercion
|
||||
- **Reduced Translation Overhead**: Eliminates need for dialect translation layer
|
||||
|
||||
**PostgreSQL Syntax Support**:
|
||||
- **Identifier Quoting**: Uses PostgreSQL double quotes (`"`) for identifiers
|
||||
- **String Concatenation**: Supports PostgreSQL `||` operator
|
||||
- **System Functions**: Full support for PostgreSQL system catalogs (`pg_catalog`) and functions
|
||||
- **Standard Compliance**: Follows PostgreSQL SQL standard and dialect
|
||||
|
||||
**Implementation Features**:
|
||||
- Native PostgreSQL query processing in `protocol.go`
|
||||
- System query support (`SELECT version()`, `BEGIN`, etc.)
|
||||
- Type mapping between PostgreSQL and SeaweedFS schema types
|
||||
- Error code mapping to PostgreSQL standards
|
||||
- Comprehensive PostgreSQL wire protocol support
|
||||
|
||||
This package provides enterprise-grade PostgreSQL compatibility, enabling seamless integration of SeaweedFS with the entire PostgreSQL ecosystem.
