Hi All, I want to use postgresql instead of sqlite, and below is how I did the settings: I am running Galaxy under the user ubuntu, so first I create the ubuntu user sudo -u postgres createuser -D -A -P ubuntu Then I create the database named galaxy_db sudo -u postgres createdb -O ubuntu galaxy_db in Galaxy configuration file, use postgresql postgres:///galaxy_db?user=ubuntu&host=/var/run/postgresql When I start Galaxy, sqlite dialect, not postgresql is selected. I am pasting part of the log below: galaxy.model.migrate.check DEBUG 2012-04-23 17:59:52,676 pysqlite>=2 egg successfully loaded for sqlite dialect galaxy.model.migrate.check INFO 2012-04-23 17:59:52,707 At database version 93 galaxy.tool_shed.migrate.check DEBUG 2012-04-23 17:59:52,718 pysqlite>=2 egg successfully loaded for sqlite dialect galaxy.tool_shed.migrate.check INFO 2012-04-23 17:59:52,730 At migrate_tools version 1 galaxy.model.custom_types DEBUG 2012-04-23 17:59:52,735 pysqlite>=2 egg successfully loaded for sqlite dialect Is there anything wrong with my configuration? Thank you. Cai
