I see multiple occurrences of
LOG: could not fork new process for connection: Resource temporarily unavailable
so indeed your process limit is too low. It's curious that OpenBSD
seems more prone than other platforms to produce a "broken pipe" error
instead of reporting the error message sent back by the postmaster ...
but there is something of a race condition there, so we can't complain
too much.
I have no idea why running the tests off ramdisk would make a difference
in the probability of this failure, but it's academic. Raise your
process limit.
