Обсуждение: Re: Adding NetBSD and OpenBSD to Postgres CI

Hi,

The openbsd/netbsd CI tasks are occasionally failing due to reaching the
process limit. See e.g.
https://cirrus-ci.com/task/5559228405907456
+psql: error: connection to server on socket "/tmp/pg_regress-nQ1wk1/.s.PGSQL.40056" failed: could not fork new process
forconnection: Resource temporarily unavailable
 

This is due to the ulimit -p 256 in .cirrus.tasks.yml not being high enough.
The ulimit on openbsd couldn't trivially be increased with ulimit, because of
hitting the hard limit.  Instead of increasing the limit in the CI script, the
CI image generation now increases the limits:
  https://github.com/anarazel/pg-vm-images/pull/129

I plan to push this patch soon.

Greetings,

Andres Freund
