Hmm, I guess it would violate POLA that the standalone server would
decide to run checkpoint in the middle of vacuum. I imagine that in
some cases the only option would be to process the tables manually, with
the ALTER TABLE/SET TYPE trick or similar (VACUUM FULL in 9.0+).
So I can see that there is no good fix for this problem, yet it is a
very inconvenient situation to be in.
