Greetings!

   Well, here is the problem:
   A "production" table has a CHECK left from "development" days and I need
to delete it. It is not a foreign key, just a silly limit on a field's
value.
   Of course, I can perform a CREATE/DROP/RENAME ritual, but would
rather not, as the table is large and it is referenced by other
tables.
   I browsed the manual and found that CHECK's are kept in pg_relcheck
and their count in pg_class.

   So, the question:
   Can I just delete the record in pg_relcheck, decrement the counter
in pg_class and enjoy the results or will it have undesirable
side-effects?
