Oh? That's interesting. It might help to patch
src/pl/plpgsql/src/pl_comp.c to show you the OID that it's unhappy about
... um ... waitasec. 7.0.* already *has* that patch. If you're getting
an error message that doesn't mention an OID, you must be running a
7.0.0 or older plpgsql. That might not play too well with a post-7.0
backend. Check the path that's defined for the plpgsql shlib.
