Synopsis
COMMIT PREPARED transaction_id
Description
   COMMIT PREPARED commits a transaction that is in
   prepared state.
  
Parameters
- transaction_id
-       The transaction identifier of the transaction that is to be
      committed.
      
Notes
   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.
  
Examples
   Commit the transaction identified by the transaction
   identifier foobar:
COMMIT PREPARED 'foobar';
