Further information

Was able to remotely connect to database from Octoprint machine using a simple python psycopg2 connect script.

!/usr/bin/python2.4

Small script to show PostgreSQL and Pyscopg together

import psycopg2

try: conn = psycopg2.connect(database='octoprint_filamentmanager', user='octoprint', password='mypasswd', host='192.168.1.22', port='5432') except: print "I am unable to connect to the database"

Looking at the Filament manager connection script it appears to be using SqlAlchemy and not psycopg2 as documented.

I have read the FAQ and provided all required information. Yes
