I have reproduced the failure and found it was code I added to pg_dump
back in 9.0.  The code didn't set the index oid for exclusion constraint
indexes.  Once these were added to the regression tests for range types
recently, pg_upgrade threw an error.

My assumption is that anyone trying to use an exclusion constraint with
pg_upgrade will get the same type of error.

Patch attached.  Should it be backpatched to 9.0 and 9.1?
