PostgreSQL doesn't offer capturing parentheses. The
regex library does offer that, but no-one has yet done
the coding to bring that functionality into
PostgreSQL.
You could do it in two steps:
1. Test using a regular expression
2. locid := substr(r,1); table := substr(r,2,1-len(r))
(better check the syntax on those).
