COMMIT PREPARED

COMMIT PREPARED commits a prepared two-phase transaction.

The function is only available in maintenance mode (when GUC parameter xc_maintenance_mode is on). Exercise caution when enabling the mode. It is used by maintenance engineers for troubleshooting. Common users should not use the mode.
Only the transaction creators or system administrators can run the COMMIT command. The creation and commit operations must be in different sessions.
The transaction function is maintained automatically by the database, and should be not visible to users.
