Mainly, would it be faster to have a separate field to store the parsed (at input) number and then query that field directly (even if it is a text field as well)? Basically cache the parse. Caching's looking tempting, but I don't know if it'll be worth it (these fields won't be searched-as-int very often compared to search-as-string, and there's potentially a lot of such fields). All I need out of it is the leading digits - I can strip them with trim(), but I can't keep _only_ those digits. The other possibility that may be of value is to write the function in C instead of pl/pgsql, which will then actually call atoi() itself. Is that going to be a better option?
