Itried setting the file=sys.stderr 

Hmm.  I can tell you that with "logging_collector = on", I would only
expect the logs to capture stderr output, not stdout.  So it makes
sense to me that plain "print" would disappear into the bit bucket.
But if you specify stderr output, it ought to work.  I don't know
enough Python to know why it's not working, but it seems to me this is
primarily a Python question not a Postgres question.  Maybe you need
an explicit fflush-equivalent step?  Dunno.
