ROLLBACK PREPARED(7) PostgreSQL 9.4.15 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.
