@vlsi Surely. Doing so brings the particular test run down to ~5:30 minutes, so a little higher than the ~3:30 minutes, but there's always some fluctuation depending on how busy my machine is at the particular time of day. I would say removing the flag here as well
https://github.com/pgjdbc/pgjdbc/blob/eaf8063ef7d87c343c7cd97833b2fc263152d893/pgjdbc/src/main/java/org/postgresql/core/SetupQueryRunner.java#L50-L51 
has overall the same effect as bringing back the case block in the switch and sits currently at ~5 minutes at my machine.

EDIT: A morning session today with the suggested changes is at ~3:30 again, so as expected.
