Well, you could adopt an actually supported release:

> ;     Dumped by pg_dump version: 9.3beta2

I'm not just being snarky: the messages you're getting here remind me of a
bug we fixed some time ago.  But even aside from this specific complaint,
the list of known data-loss bugs in 9.3beta should terrify you.  Why in
the world are you still using it?

Hmm,  seems -n is not the same in pg_dump and pg_restore. If you do a
dump with the
-n switch you get the SCHEMA creation in the restore. If you use the -n
on the restore
you get the contained objects but not the SCHEMA creation statement.
Might try generating a TOC from your dump and then pulling the entry for
schema
sch1 and put it at the top of the TOC you generated below.
