Ok, but then it should be sufficient to recreate the txt2txtidx function
and/or the index after a change of parser and dictionaries. So generally
spoken, the index function approach to tsearch works, if you take care of
that. I gladly recreate the function and/or index from time to time, if I
can do without that additional column, bloated dump and slow trigger.

This is very good news, as this is a very easy approach to having an easy to
use fulltextsearch in postgresql.
