Thanks, that makes sense. I think I'll go with the cast approach, I
don't really need stemming anywhere.

Something funny going on with my full text search.. and I have no idea what.
The way to debug this sort of thing is generally to look at what tsquery
you're actually getting. I get
regression=# select to_tsquery(unaccent('a:*'));
NOTICE: text-search query contains only stop words or doesn't contain lexemes,
ignored
to_tsquery
------------
(1 row)
regression=# select to_tsquery(unaccent('an:*'));
NOTICE: text-search query contains only stop words or doesn't contain lexemes,
ignored
to_tsquery
------------
(1 row)
regression=# select to_tsquery(unaccent('ana:*'));
to_tsquery
------------
'ana':*
(1 row)
Of course, only the last is going to match 'ana'.
So you need to use a text search configuration in which a/an are
not stop words. Or possibly you could cast the unaccent result
directly to tsquery rather than passing it through to_tsquery(),
though likely that would just have a different set of failure modes
with queries where you do wish stemming would occur.
The problem with "no" seems to be the same.
