ROLLBACK PREPARED(7)                                      SQL Commands                                      ROLLBACK PREPARED(7)



NAME
       ROLLBACK PREPARED - cancel a transaction that was earlier prepared for two-phase commit


SYNOPSIS
       ROLLBACK PREPARED transaction_id


DESCRIPTION
       ROLLBACK PREPARED rolls back a transaction that is in prepared state.

PARAMETERS
       transaction_id
              The transaction identifier of the transaction that is to be rolled back.

NOTES
       To  roll  back  a  prepared  transaction, you must be either the same user that executed the transaction originally, or a
       superuser. But you do not have to be in the same session that executed the transaction.

       This command cannot be executed inside a transaction block. The prepared transaction is rolled back immediately.

       All currently available prepared transactions are listed in the pg_prepared_xacts system view.

EXAMPLES
       Roll back the transaction identified by the transaction identifier foobar:

       ROLLBACK PREPARED 'foobar';
