Thanks for the explanation as that helped fixed the select. I just need to use: atdev=# update pg_cast set castcontext = 'i' where castsource ='int'::regtype and casttarget = 'bool'::regtype; >> HINT: No operator matches the given name and argument type(s).

It expects a zero and one int for booleans like SQL Server does, because the postgres db population was done that way. The equivalent SQL Server hibernate generated query is quite different. My thinking is that this cast is the only viable option, compared to changing 0 and 1 to '0' and '1' a couple of million times in a big DDL, on a couple hundred boolean columns. I'd need a special regex for every table that'd be a nightmare to maintain. So I'm good for now, thanks all. -- Sent via pgsql-general mailing list (pgsql-general@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-general
