That would actually not be a bad idea, perhaps, because the method we're using right now requires that the linker not bitch about unresolved symbols at build time, which is a really bad thing that I'd prefer to turn off. It's still not a very back-patchable answer, but it's something that we could get to in HEAD without a huge amount of work. regards, tom lane -- Sent via pgsql-hackers mailing list (firstname.lastname@example.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
