db-apply-migration

To safely apply a database migration, this process acquires a PostgreSQL advisory lock, creates pre- and post-migration schema snapshots, and executes the SQL script within a transaction to ensure data integrity and prevent concurrent modifications.

An advisory lock prevents concurrent database migrations by blocking other migration processes from executing simultaneously. This ensures only one migration script runs at a time, protecting the PostgreSQL schema from race conditions and conflicting modifications.

Yes, you can automatically rollback a failed SQL migration script. The process executes the migration within a transaction, automatically rolling back changes if query syntax errors or connection failures occur, while providing clear manual rollback instructions.

If a database migration encounters a connection failure or query syntax error, the transaction is automatically rolled back. The process then utilizes a retry strategy to attempt the migration again, ensuring transient issues do not corrupt your PostgreSQL schema.

Yes, pre- and post-migration schema snapshots are created to facilitate safe database rollback. These snapshots generate a diff of the schema changes, allowing you to audit what was modified and easily revert the database if issues arise.
