Once nice touch is that booleans and numbers will be accepted by Pg if
they're escaped and quoted like strings. So, in PHP, I always run
EVERYTHING through a wrapper db_quote() function that returns
something like ("'" . pg_escape_string(foo) . "'") (or its equivalent
in MySQL, etc) and just call it fixed. Of course, I do type checks
for user feedback and such as well, but in case something slips
through, it's all escaped.
