ROLLBACK PREPARED(7)              PostgreSQL 14.19 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.
