For stuff that involves database accesses, plpgsql will almost always
win, because it's the only one we have that caches query plans.
If you are doing simple calculations, text-mashing, etc, then you might
be best off with plperl or pltcl (choose according to taste). SQL and
plpgsql are overkill for simple arithmetic and don't have very extensive
text-manipulation capabilities.
