I have fixed pg_upgrade in git-head with the attached patch, which
prepends default_transaction_read_only=false to PGOPTIONS. I prepended
rather than appended because if PGOPTIONS had
default_transaction_read_only=true, I didn't want to override that.
While pg_dumpall would override that, that is more of an implementation
detail of having to set the value at the session level, rather than a
desired behavior.
