COMMIT(7) PostgreSQL 12.5 Documentation COMMIT(7)

COMMIT - commit the current transaction

COMMIT [ WORK | TRANSACTION ] [ AND [ NO ] CHAIN ]

COMMIT commits the current transaction. All changes made by the transaction become visible to others and are guaranteed to be durable if a crash occurs.

WORK
TRANSACTION
Optional key words. They have no effect.

AND CHAIN

If AND CHAIN is specified, a new transaction is immediately started with the same transaction characteristics (see SET TRANSACTION (SET_TRANSACTION(7))) as the just finished one. Otherwise, no new transaction is started.

Use ROLLBACK(7) to abort a transaction.

Issuing COMMIT when not inside a transaction does no harm, but it will provoke a warning message. COMMIT AND CHAIN when not inside a transaction is an error.

To commit the current transaction and make all changes permanent:
COMMIT;

The command COMMIT conforms to the SQL standard. The form COMMIT TRANSACTION is a PostgreSQL extension.
