99% of the people installing with Postgres as the backend will not need to change the tsearch2 schema, and it's kind of confusing to have it in there. Hide it from the installer such that the install will fail and it will be revealed only if PG is < 8.3 and the tsearch2 schema cannot be found (e.g. it's not 'public' or 'pg_catalog')
