text search configuration missing while migration from 8.3 to 9.4

[Julie Nishimura]

Hello, we recenlty created fresh install of 9.4, created new dbs, and pg_dumped 
and restored correspondent dbs from 8.3 (pg_dump|psql, being on target). Now 
we've noticed that some of `pg_catalog.pg_ts_config` and pg_ts_dict tables are 
missing, making text search on 9.4 very slow. We tried to insert missing 
records from pg_catalog.pg_ts_config, but it does not help. What is the proper 
procedure for it? Please help, thanks!
