Sure, change it and re-compile. But be aware that increasing it will
probably increase the cost of some other stuff, so it's a tradeoff.
If this is that complex though you very likely would do better in
plperl, especially if you could pre-compile the RE's. AFAIK there's no
way to do that in Postgres, though it might be interesting to add that
ability.
