What a conundrum! :>
If it's any help, our support for MySQL v4.1 is much much much more likely to happen in the near-ish term than PostgreSQL support. As in, it's pretty much a sure thing at this point, and it's only a matter of fitting it in with all of the other big ticket requests customers have.
PostgreSQL is a very fine database server (I've begun writing my scripts to work with both, and recognize that Postgres has some things going for it that even the latest version of MySQL doesn't), but the fact remains that our customers' scripts almost all work well with MySQL, and don't even take advantage of those features. I suppose it's a chicken and egg type problem, but until there is sufficient demand for PostgreSQL we're taking a wait and see attitude.
As for Ruby on Rails... It is, indeed, very cool - a technology that even I wish we could support. It's probably a bit easier for us to offer versus PostgreSQL, but it's still very new.
I imagine a lot of these oft-requested features will become easier for us to implement once the next stable Debian release comes out, though our admins would know more about the specific hang-ups than I.
