SYNOPSIS
END [ WORK | TRANSACTION ]
DESCRIPTION

crash occurs. This command is a PostgreSQL extension that is equivalent to COMMIT(7).
PARAMETERS

Optional key words. They have no effect.
NOTES
Use ROLLBACK(7) to abort a transaction.
Issuing END 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:
END;
COMPATIBILITY
