Postgresql support shouldn't be in devstack. If we're taking a tier 2 approach, someone needs to carve out database plugins from devstack and pg would be one (as could be galera, etc). This historical artifact that pg was maintained in devstack, but much more widely used backends were not, is part of the issue. It would also be a good unit test case as to whether there are pg focused folks around out there willing to do this basic devstack plugin / job setup work. -Sean -- Sean Dague http://dague.net __________________________________________________________________________ OpenStack Development Mailing List (not for usage questions) Unsubscribe: openstack-dev-requ...@lists.openstack.org?subject:unsubscribe http://lists.openstack.org/cgi-bin/mailman/listinfo/openstack-dev
