Um, I think we would want to still have the ability to not need to
frequently vacuum known frozen databases.
Could we set datvacuumxid to frozenxid after freezing template0
and making it non-connectable ? There was discussion about making
a non-connectable db connectable, one step would be to set datvacuumxid
to currentxid.
Then the rule would be: ignore db's that have datvacuumxid == frozenxid.
(only readonly db's would be allowed to have datvacuumxid == frozenxid)

PS: I agree that the rename from datfrozenxid to datvacuumxid should be
undone
