Transactions: BEGIN, COMMIT, ROLLBACK - PostgreSQL for Developers
Transactions: BEGIN, COMMIT, ROLLBACK - part of PostgreSQL for Developers.
PostgreSQL from the inside out - fundamentals through internals and ops.
In this lesson:
Any two writes that must succeed or fail together must be inside an explicit BEGIN / COMMIT block
Statements outside a transaction block auto-commit instantly — there is no undo path
Use SAVEPOINT when you need partial rollback inside a long transaction without aborting everything
A ROLLBACK does not run automatically on error in psql scripts — check for explicit error handling
