NAME

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  immedi-
       ately.

       All currently available prepared transactions are listed in the pg_prepared_xacts system view.
