Same issue as pgmigrate: *sql.DB is a connection pool, so each call may land on a different connection. Migrations need a pinned connection for session state (SET search_path, temp tables, etc.) to persist across sequential calls. *sql.Conn (from db.Conn(ctx)) pins one underlying connection for its lifetime.
sqlmigrate
Database-agnostic SQL migration library for Go.
Backend packages
Each backend is a separate Go module to avoid pulling unnecessary drivers:
| Package | Database | Driver |
|---|---|---|
| pgmigrate | PostgreSQL | pgx/v5 |
| mymigrate | MySQL / MariaDB | go-sql-driver/mysql |
| litemigrate | SQLite | database/sql (caller imports driver) |
| msmigrate | SQL Server | go-mssqldb |
| shmigrate | Shell scripts | (uses native CLI) |
CLI
The sql-migrate CLI uses shmigrate to generate shell scripts for managing migrations without a Go dependency at runtime.
