COMMIT(7) PostgreSQL 11.5 Documentation COMMIT(7)

COMMIT - commit the current transaction

COMMIT [ WORK | TRANSACTION ]

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.

Use ROLLBACK(7) to abort a transaction.

Issuing COMMIT when not inside a transaction does no harm, but it will provoke a warning message.

To commit the current transaction and make all changes permanent:

COMMIT;

The SQL standard only specifies the two forms COMMIT and COMMIT WORK. Otherwise, this command is fully conforming.
