Remove the tsearch2 backend The documentation within the tsearch2 backend labels it as being experimental and that it should not be used. The have_backend() function in roundup.backend returns False indicating that it does not exist and is labeled as "currently not working". The PostgreSQL website also seems to indicate that it has been deprecated since v8.3 when text searching was integrated into the core[1]. Considering all this, it seems like the best option is to just remove the tsearch2 backend. [1] http://www.postgresql.org/docs/9.4/static/tsearch2.html
