I have a database running very happily in 8.2 (to be upgraded soon). The system was installed with tsearch2 enabled, however, we have yet to use it. I am going through an effort to reduce "cruft" in the database, which includes four tables: pg_ts_cfg, pg_ts_cfgmap, pg_ts_dict, pg_ts_parser. Are these tables safe to drop? Will the remnants of tsearch2 be anywhere else in the database if it was never used?
Thanks folks --
