This assumes that the search path at creation time has something to do
with the path you'd like to use at execution, which is unlikely to be
the case in existing pg_dump output, to name one example.  I don't
really want to get into doing the above.

Well, security definer functions can't be inlined anyway, so as long as
you only try to do this for sec-def functions it wouldn't be an issue.
I just think it's too big a departure from existing behavior, and will
probably break more things than it fixes.
