4 ABORT — abort the current transaction
8 ABORT [ WORK | TRANSACTION ] [ AND [ NO ] CHAIN ]
12 ABORT rolls back the current transaction and causes all the updates
13 made by the transaction to be discarded. This command is identical in
14 behavior to the standard SQL command ROLLBACK, and is present only for
21 Optional key words. They have no effect.
24 If AND CHAIN is specified, a new transaction is immediately
25 started with the same transaction characteristics (see SET
26 TRANSACTION) as the just finished one. Otherwise, no new
27 transaction is started.
31 Use COMMIT to successfully terminate a transaction.
33 Issuing ABORT outside of a transaction block emits a warning and
34 otherwise has no effect.
43 This command is a PostgreSQL extension present for historical reasons.
44 ROLLBACK is the equivalent standard SQL command.
