Problem reloading regression database - Mailing list pgsql-hackers

I am testing pg_upgrade.  I successfully did a pg_upgrade of a 7.2
regression database into a fresh 7.2 install.  I compared the output of
pg_dump from both copies and found that c_star dump caused a crash.  I
then started doing more testing of the regression database and found
that the regression database does not load in cleanly.  These failures
cause pg_upgrade files not to match the loaded schema.

Looks like there is a problem with inheritance, patch attached listing
the pg_dump load failures. I also see what looks like a crash in the
server logs:

    DEBUG:  pq_flush: send() failed: Broken pipe
    FATAL 1:  Socket command type 1 unknown

Looks like it should be fixed before final.
