Yes, that is the patch.

Uh, right now it is printing:
-- pg_dump version: 9.0devel---- remote database version: 9.0devel (90000)
That is in the SQL output file.

So you are saying if you run pg_restore on the SQL dump file, it doesn't
pick up the version? I didn't even know pg_restore could do that for
text dump files. In fact, I can't get it to work:
$ pg_dump -v test > /rtmp/x...$ pg_restore -l /rtmp/x -d testpg_restore: [archiver] input file does not appear to be a
validarchive
I obviously am missing something.
