Comment 1 for bug 860159

I've attached a branch with the Postgres support code that I've cooked up.

Some notes:

1. You must install Storm trunk (or v. 0.19 whenever that is released) as version 0.18 is broken w/regards to Postgres and UUID columns.

2. I haven't adapted the test suite to run against Postgres, yet, but my own external integration tests pass (which encompass quite a bit of functionality).

3. There is now an alternate mailman_pg.sql file which is used to create the tables. Currently, two foreign key constraints are commented out because those are violated in Mailman 3 (apparently this doesn't bother SQLite). Some column TYPES are different from mailman.sql. Classes are created in a slightly different order due to FK constraint creation requires the referenced table to actually exist. The primary key indexes defined after each class are probably redundant, as those are created automatically for SERIAL columns defined as PRIMARY KEY in Postgres.

4. Probably more FK constraint violations exist that my tests haven't uncovered.
