I don't know exactly how the launcher would behave offhand, but it's clear that not being able to VACUUM one table in one database (because it has a corrupt index) ultimately risks the availability of every database in the cluster. Many installations receive little to no supervision, so it may just be a matter of time there. That is certainly a bad thing. -- Peter Geoghegan
