Robert, I think that the core extension if pretty uncontroversial, modulo some minor issues. It's the upgrade process that's more controversial. I think the case can be made to accept even that part as Dim has written it, because it is pretty much the bare minimum that other solutions could be built on top of and improve upon. But if not, I think that's the only part the one might really look at as something to omit for 9.1.

Dim, I haven't followed that closely lately, but is the ALTER EXTENSION UPGRADE bit still a separate patch?

Best,

David
