Python Psycopg2 - Interface Error : Connection already closed

[knobbyknees]

I'm not sure if this is the right group, but I'm hoping it is...

Basically, I'm trying to use pgloader, which depends on python and
psycopg2. After banging my head against a wall, I found this:

Found this:
http://www.mail-archive.com/[email protected]/msg13209.html

Although, the suggestion didn't work for me at all...

Running this command:
/usr/bin/pgloader -c /var/mybin/pgconfs/fr.conf

Yields this in the pgloader.log (with the process just hanging)

more /tmp/pgloader.log

....


This is what I see for the traceback:
Traceback (most recent call last):

in terminate
self.db.close()
File "/usr/lib/pymodules/python2.6/pgloader/db.py", line 103, in
close
self.dbconn.close()


I'm at a total loss here.... Can anyone please help me out?

Hi knobbyknees,
I can't help you with this problem, but the folks on the psycopg2
mailing list are probably a much better crowd to ask:
http://lists.initd.org/mailman/listinfo/psycopg


Good luck
