XXX isn't a signature, it's a conventional marker for a "Hey! This is
broken! FIX ME!" kind of comment.  I think the original idea was you
could do "grep XXX *.c" if you were idly looking for problems to work
on.  Some projects use "FIXME" in the same way.

The only signatures I've seen in the Postgres code are initials at the
ends of comments.  XXX usually goes at the front of a gripe.
