Ooops, now it seems i have an issue.
The whole point i went this way, was because i wanted to have a schema-only dump first,
in order to clean it from everything it had to do with contrib/tsearch2, contrib/intarray, dbsize
as well as to edit the triggers (substitute tsearch2 with tsvector_update_trigger), update the tsearch2 indexes
to use GIN.

So the plan was:
1) i take the schema-only dump
2) i edit the schema dump
3) i create the db
4) import _int.sql
5) import the schema
6) restore data
This procedure is kind of the official upgrade noted on http://www.sai.msu.su/~megera/wiki/Tsearch2_83_changes
and described on http://sql-info.de/postgresql/notes/converting-tsearch2-to-8.3.html

I am reading this link right away.

Any thoughts very welcome.
