Hmm, this solution is not very friendly to the goal of reducing test
runtime, particularly since the new test creates a nontrivial-sized
table. Maybe we can find a better alternative. Can we use some wait
logic instead? Maybe something like grab a snapshot of running VXIDs
and loop waiting until they're all gone before doing the vacuum?
Also, I don't understand why pg_relation_size() is not a better solution
to determining the table size compared to explain.
