I wonder if we should have a mode for plpgsql functions where all name
lookups are done at definition time So the bar() function would be
resolved to bar.bar() and stored that way permanently so that pg_dump
dumped the definition as bar.bar().
That would be probably just as good as setting the search path on the
function for most users and better for some. It would have the same
problem with dynamic sql that a lot of things have though.
