ABORT
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 , and is present only for historical reasons.
Notes
Use COMMIT to successfully terminate a transaction.
Issuing ABORT outside of a transaction block emits a warning and otherwise has no effect.
Compatibility
This command is a PostgreSQL extension present for historical reasons. ROLLBACK is the equivalent standard SQL command.
