Uff, I had no idea that Postgres v15 introduced WAL_LOG and changed the defaults from FILE_COPY. For (parallel CI) test envs, it make so much sense to switch back to the FILE_COPY strategy ... and I previously actually relied on that behavior.

Raised an issue in my previous pet project for doing concurrent integration tests with real PostgreSQL DBs (https://github.com/allaboutapps/integresql) as well.
