dump/reload is *the* biggest problem I've had with tsearch2 so far. But
it hasn't been with the actual data - it's been the functions, and only
when migrating between versions. But solving dump/reload reliably is one
of the main things I'm hoping for in 8.3 ;-)

As for a nother use-pointer, I use different configurations in the same
database - but only one per table. I explicitly use the to_tsvector that
specifies a configuration always - to avoid surprising myself.

I don't use the functional index part, but for new users I can see how
that's certainly a *lot* easier. Requiring the specification of the
configuration explicitly when creating this index I don't see as a big
problem at all - compared to the work needed to set up triggers. But
it's nice not to have to do it when querying. But wouldn't that be
solved by having to_tsvector() require the configuration, but
to_tsquery() and plainto_tsquery() not require it?
