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,
and is present only for historical reasons.
Parameters
WORK TRANSACTION
Optional key words. They have no effect.
Notes
Use COMMIT 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.
