Hi,

I've seen this postfix bug report only now that I've received
independent complaints about the problem via the PostgreSQL IRC.
I've forwarded the problem to the pgsql-hackers list and a fix is
being prepared that should hopefully appear in libpq5 9.4.1.

Thanks for the /etc/passwd hint, I was somewhat stuck in my own
debugging attempts, and this explained the problem pretty well.
