I think Tom Lane found the "problem". It has to do with the semaphores
taking up FD's.
Hm, no, because:
Yes, saw that after I posted my answer.
Sure. I compiled pgsql 12 and this is the complete logfile after
starting up the server the first time with log_min_messages=debug2:
2020-01-04 01:03:14.492 CET [14906] DEBUG: max_safe_fds = 984,
usable_fds = 1000, already_open = 6
That's pretty much the same thing we see on most other platforms.
Plus your configure log shows that SysV semaphores were selected,
and those don't eat FDs.
Yes, it looks "normal".
Apparently, in the environment of that TAP test, the server has more
open FDs at this point than it does when running "normally". I have
no idea what the additional FDs might be.
Well it's running under cron if that makes a difference and what is the
TAP-test using? perl?
