Has anyone dealt with the issue of using tsearch2 with statute cites
yet? Do you have a sample dictionary or any tips? We need to confirm
with the users, but I think desired behavior is that a statute cite of
'813.12(1)(am)' should be found on any leading portions -- that is,
any of the following search arguments should find it:
813
813.12
813.12(1)
813.12(1)(am)
On the other hand, a document containing '813.12(1)' (without the
'(am)' should be found by the first three of the above, but not the
last.
This would seem to require using a slightly different dictionary set
to create the tsquery than to create the tsvector. There's no problem
with that, is there?

Kevin,
in 8.4 it'd be possible to use prefix search, see our presentation
about GIN at PGCon 2008. For now you can use dict_regexp, which
allows to use perl's regular expressions. Get it from
http://vo.astronet.ru/arxiv/dict_regex.html
