I'm not sure if it's what you ask for, but there _is_ a clear difference
between the procedural languages -- I've had a 10x speed increase from
rewriting PL/PgSQL stuff into PL/Perl, for instance. I'm not sure which ones
would be faster, though -- I believe Ruby is slower than Perl or Python
generally, but I don't know how it all works out in a PL/* setting.
