ABORT — abort the current transaction
ABORT [ WORK | TRANSACTION ] [ AND [ NO ] CHAIN ]
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.
WORKTRANSACTIONOptional 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) as the just finished one. Otherwise,
no new transaction is started.
Use COMMIT to successfully terminate a transaction.
Issuing ABORT outside of a transaction block
emits a warning and otherwise has no effect.
To abort all changes:
ABORT;
This command is a PostgreSQL extension
present for historical reasons. ROLLBACK is the
equivalent standard SQL command.
