Sorry, forgot to mention that:
logging_collector = on # Enable capturing of stderr and csvlog
Infact I was thinking of the other way, to switch it off and somehow display the
stderr(or syslog) directly on console (rather than writing to a file) to see if
it helps.

Hmm, what about logging_collector? (Or it might be called
redirect_stderr, depending on which PG version this is.)
If it's currently off, see whether turning it on improves matters.
