To commit 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 committed immediately. All currently available prepared transactions are listed in the pg_prepared_xacts system view.
