It won't fit into the existing code easily, but it could probably be done.
I toyed around with making the regex more robust, but three things
stopped me:
1) The "star at start" and "star at end" catches probably 99% of the cases,
and is way better than what we have now, so better a bird in the hand...
2) It would be a lot more work to send it to the backend or import some
of the regex code.
and most importantly:
3) It would require yet more arguments to pg_dump. The moment we start allowing
regular expression characters that are also valid identifier names (e.g. "."
and "_") we'll need some way to tell pg_dump whether we mean a literal search
or a regular expression one. Which probably means more arguments or at least
modifying the existing one in a possibly nonintuitive, and definitely more
complex, manner. I'm open to suggestions, however, but I don't want to make
things too byzantine for the users.
