I'm working on Postgres support. It certainly doesn't work yet, mostly because the database creation is very SQLite specific, both the schema definitions which are in raw SQLite-flavored SQL, and some supporting code. I'm currently creating a mailman_pg.sql file to be used if a postgres database URL is given. There's probably a better way to do it, and I'd hazard to guess that would have been using a different ORM. -- You received this bug notification because you are a member of Mailman Coders, which is subscribed to GNU Mailman. https://bugs.launchpad.net/bugs/856004 Title: "OperationalError: database is locked" encountered under very light load while using REST API To manage notifications about this bug go to: https://bugs.launchpad.net/mailman/+bug/856004/+subscriptions
