you had to apply patch to 7.4.1 db before dumping or use regprocedure_update.sql
to update your live 7.4.1 database ! pg_dump (pg_dumpall) has nothing with
the problem. After applying patch and dumping db you have OID-free db and
should have no problem !

No, if you have OIDs in db pg_dump* will dump them. Try regprocedure_update.sql
and read http://www.sai.msu.su/~megera/postgres/gist/tsearch/V2/docs/tsearch-V2-intro.html

If you have 7.4.1 db running you might go way described earlier.
