go-migration

Reversible PostgreSQL schema migrations in Go are designed with clear rollback strategies to undo additive changes. This approach ensures safe database schema evolution by handling both the forward migration and the rollback logic for non-reversible operations.

Data transformations during a database migration are handled using either SQL or Go code directly within the migration files. This allows you to safely migrate and transform complex data structures while maintaining backward compatibility.

Idempotent database migrations for Go applications can be designed to run safely multiple times without causing duplicate schema changes or data corruption. This focuses on safety by ensuring repeated execution yields the same database state.

Database migrations manage backward-compatible schema changes by focusing on additive operations, such as adding new tables or columns, rather than destructive modifications. This ensures minimal downtime and maintains application stability during the transition.

Non-reversible database migrations involve operations that cannot be undone, requiring clear rollback strategies to mitigate risks. When a direct reversal is impossible, the migration design provides alternative compensating actions or explicit documentation to handle the schema state safely.
