I'm testing pg_upgrade out and ran into a couple of problems. First when I did pg_upgrade --check I got the tsearch2 tables preventing the upgrade from happening:
Database: testdatabase
public.pg_ts_dict.dict_init
public.pg_ts_dict.dict_lexize
public.pg_ts_parser.prs_start
public.pg_ts_parser.prs_nexttoken
public.pg_ts_parser.prs_end
public.pg_ts_parser.prs_headline
public.pg_ts_parser.prs_lextype
For testing, at this point I really didn't care about tsearch, so I simply dropped those tables so I could revisit them later -- however, I'm confused about these tables in general, both pg_catalog.pg_ts_parser and public.pg_ts_parser exist with different, albeit similar, schemas. I think that the table in public is no longer used and was a remnant from pre-8.3 when tsearch2 wasn't part of the distribution, can anyone confirm this?
Anyway, after removing the tsearch tables, I did pg_upgrade --check again and it said the clusters were compatible. I proceeded to run the upgrade command and it bombed out in the "Restoring user relation files" section. I've included some output below, any advice on what is going on? It seems something is messed up in either the check logic or actual migration code.
