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. -- Álvaro Herrera https://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
