Disable the test, it is mostly pointless.

Only tables that regularly receive updates and deletes need to be vacuumed.
A table that is never modified needs to be vacuumed at most once during its lifetime
for transaction wraparound, but there are other checks for problems with that.

Alternatively, you can just manually vacuum all tables once - if all it
checks is if it *ever* has been vacuumed.
