I don't understand. Why use "it_IT.ISO8859-1"? You just need to know
the language, so "it" is enough. The _IT part specifies that it's the
italian spoken in Italy. This may be irrelevant in most cases, but
consider that pt_PT and pt_BR are AFAIK somewhat different languages.

I very much doubt that the different spanishes are any different in the
stemming rules, so there's no need for es_ES, es_PE, es_AR, es_CL etc;
but in the case of portuguese I'm not so sure. Maybe there are other
examples (like chinese, but I'm not sure how useful is tsearch for
chinese).

And the .ISO8859-1 part you don't need at all if you accept that the
files are UTF8 by design, as Tom proposed.
