ABORT - abort the current transaction

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

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.

       To abort all changes:

           ABORT;

       ABORT - abort the current transaction

       Use COMMIT to successfully terminate a transaction.

       Issuing ABORT outside of a transaction block emits a warning and otherwise has no effect.

       WORK
       TRANSACTION
           Optional 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 SETTRANSACTION) as the just finished one. Otherwise, no new transaction is
           started.
