NAME

       ABORT - abort the current transaction

SYNOPSIS

       ABORT [ WORK | TRANSACTION ]

DESCRIPTION

       ABORT  rolls back the current transaction and causes all the updates made by the transaction to be discarded.  This command is identical in
       behavior to the standard SQL command ROLLBACK [rollback(7)], and is present only for historical reasons.

PARAMETERS

       WORK

       TRANSACTION
	      Optional key words. They have no effect.

NOTES

       Use COMMIT [commit(7)] to successfully terminate a transaction.

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

EXAMPLES

       To abort all changes:

       ABORT;

COMPATIBILITY

       This command is a PostgreSQL extension present for historical reasons. ROLLBACK is the equivalent standard SQL command.
