Could someone clarify the info in this paragraph:
"Note that, due to a system catalog change, an initdb and database
reload will be required for upgrading from 9.0Beta1. We encourage
users to use this opportunity to test pg_upgrade for the upgrade from
Beta2 or an earlier version of 9.0. Please report your results."
This suggests that the system catalog change only occurred in Beta2,
not Beta3. So if that's the case, why would I want to test pg_upgrade
going from Beta2 to Beta3 if they use the same system catalog layout?
