[GENERAL] Is dropping pg_ts_* harmful?

[Eric Brown]

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 --
