I _think_ the way round this is to drop all the tsearch2 objects - you
should have an untsearch2.sql file in a contrib directory somewhere
which contains the appropriate statements. This does of course cascade
to tsvector columns, which you will have to recreate and repopulate.
FWIW I put all tsearch-related objects into their own schema, and
recreate this before restoring other data to a fresh database.
