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 pre-
       pared transaction is rolled back immediately.

       All currently available prepared transactions are listed in the pg_pre-
       pared_xacts system view.

EXAMPLES

       Roll back the transaction identified by the transaction identifier foo-
       bar:

       ROLLBACK PREPARED 'foobar';
