I'd be inclined to make it only take 2 args, table, col where table can be
namespace qualified. This allows people who arn't namespace aware to just do
SELECT pg_get_serial_sequence('mytable','mycol') and have it return the
correct item following searchpath.. I would think this would then become
consistant with the standard behavior. Not to mention it would also allow
for easier moving schema form one namespace to another..
