NAME¶ROLLBACK_PREPARED - cancel a transaction that was earlier prepared for two-phase commit
ROLLBACK PREPARED transaction_id
DESCRIPTION¶ROLLBACK PREPARED rolls back a transaction that is in prepared state.
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';
COMPATIBILITY¶ROLLBACK PREPARED is a PostgreSQL extension. It is intended for use by external transaction management systems, some of which are covered by standards (such as X/Open XA), but the SQL side of those systems is not standardized.
