ROLLBACK PREPARED(7)	 PostgreSQL 17.5 Documentation	  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';

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.
