ouch. could mucking with a configuration create a corrupt index?
Depending on what you mean 'corrupted'. It will not corrupted as non-readable
or cause backend crash. But usage of such tsvector column could be limited -
not all words will be searchable.
Am I correct to think of this like changing collations leaving your btree
index "corrupt"? In that case it probably won't cause any backend crash either
but you will get incorrect results. For example, returning different results
depending on whether the index or a full table scan is used.
You're correct. But we can't defend users from all possible errors.
Other side, that we need somehow to help user to identify what fts
configuration was used to produce tsvector. For example, comment on
tsvector column would be useful, but we don't know how to do this
automatically.

Oleg
