This will work (AFAICT, _and_ as far as I've used it): the regex-syntax
of Python is a superset of the regex-syntax of PostgreSQL (both are
based on PCRE, not on the library, but the syntax), and as such you'll
possibly do "too much" quoting, but never too little when simply using
the Python-builtin.
