[Bug 856004] Re: "OperationalError: database is locked" encountered under very light load while using REST API

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.
