Oh, I failed to understand completely the purpose of firstDelBlock then.
Anyway, there's still a big problem with this patch: the pg_depend
information gets messed up after CLUSTER, so a clustered table cannot be
dropped. I don't know why is this.
As I said yesterday, I'm going on vacation tomorrow, and probably will
not fix this issue. I can look into it when I'm back, on two weeks.
I attach a little doc patch.
