Could you post the regression test output with the timings? Unless it's AV, I don't see why a windows VM with a moderate amount of memory should take that long. Do the test times get less bad if you use PG_TEST_USE_UNIX_SOCKETS=1 PG_REGRESS_SOCK_DIR: "c:/some-dir/"? I see there's reports that the connection-timeout problem can be a lot worse on windows, because several applications, e.g. docker, add additional names for localhost. Are there any non-commented entries in C:\Windows\System32\drivers\etc\hosts > Does it get better with the attached patch? I pushed something like it now - seemed to be no reason to wait, given it makes think less slow on my VM. Greetings, Andres Freund
