[firebird-support] change a trigger that I create with RDB $ SYSTEM_FLAG = 1.

 Regards,
how can I change a trigger that I create with RDB $ SYSTEM_FLAG = 1.
He believes it in this way so as not to allow the modification of the data of a 
table that stores the log.
Now I know it's a mistake to place the field RDB $ SYSTEM_FLAG = 1, but I need 
to reset it to 0 to be able to modify it.
