Ah, that explains a good deal. You were lucky that the 6.5.3 shlib was
just incompatible enough to fail cleanly, and not to do anything really
screwy :-(

BTW, the recommended way to crank up plpgsql or other PL languages is
to use the 'createlang' script, which has a slightly better chance of
getting this sort of detail right.
