pg_upgrade (Checking for reg* data types)

Hi All,

I am trying to upgrade Postgresql 11.5 to 12 RC1, OS Centos 6. Running
pg_upgrade with --check it fails with "Checking for reg* data types in user
tables" The table listed are: pg_ts_dict,pg_ts_parser. Trying to drop the
tables I get msg " permission denied: "pg_ts_dict" is a system catalog" I
also for same reason can not remove the oids "ALTER TABLE pg_ts_parser set
without oids;"

From pg_catalog.pg_extension the following are listed:
plpgsql,pg_stat_statements,tablefunc. So the Text search extension is not
in use.

This database was upgrade since Postgresql 8.3 by using "pg_dumpall -p 5432
| psql -d postgres -p 5433" and not pg_upgrade.
