However, note that various unfixed bugs in psycopg2 make this feature nearly unworkable on that platform since psycopg2 raises the "connection lost" errors at random times. however, youre dealing with a plain database timeout issue. for that, auto-reconnect isnt needed; you use the "pool_timeout" option documented at http://www.sqlalchemy.org/docs/04/dbengine.html#dbengine_options (similarly for 0.3). --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "sqlalchemy" group.
