Yup it's been asked and answered on this this.
Please search on SQL, pluggable DB, and FS refactoring. It looks like
you may have started such a search.
The Subversion FS is not as trivial as some might think. But I'm quite
confident we will get there.
There are a number of things that must happen first.
Like Subversion 1.0. :-)
I'd like to finish my pluggable-fs document:-)
This discussion should be taken off-list for now IMO. However, I haven't
the time now to discuss it.
Feel free to talk amongst yourselves.

Pop goes the gat ... ster:-)

I'm against supporting any one DB over another. Not that it is easy.
But it is doable.
My initial support list is MySQL, Oracle, and SQLServer.
I'm not against PostgreSQL at all. I haven't worked with it. I know
Sander Striker likes it. He has also applied brain cells to the problem
of a SQL based FS. Last I heard it didn't scratch *my* major itch.
As for maturity. I can only say that I have a MySQL DB that has been up
for 2 years. That's mature enough for me. If by maturity you mean
features then OK maybe. But perhaps you should go to the MySQL site and
have a gander at what's been happening in that world. Besides
tablespaces, "connect by prior" capability I believe might be handy (not
100% sure yet). AFAIK only Oracle has it. If you are referring to
MySQL's transaction support not being there. Don't even go there! A
quick Google should put that to rest.
What platform are you on that Postgre supports and MySQL doesn't? Oh
wait just looked at your e-mail. Would it be sco?
I'm really sorry that I can't go into more detail or have a discussion
on it right now:-(
But if *you* are serious about pitching in on a SQL FS make sure you
read up on the Subversion FS before you say for sure. If you're looking
for someone else to do it, please be patient.
PS I would be thrilled if someone would round up all the SQL related
threads and post them in the FAQ. Yes I know that should be me.
