This had 1 flake, not sure if that's expected or not?

[kegsay]

Unsure. The increases concurrency means we see different kinds of flakes from before. They are always the partial state join tests though, and they've passed in the past, so tempted to merge and ignore, but this isn't my project :D

The cause of the flakiness was terribly slow partial state tests, caused by the reduced connection pool limits on postgres mode. It's now only reducing the connection pool when running with workers.
