I spoted the news on Josh Berkus's blog

It's pretty exciting to have all of these open source database
developers in one place. So far: HSQLDB, Derby, SQLite, Firebird,
Ingres, us (PostgreSQL) and of course a huge MySQL contingent (they're
one of the conference sponsors). It's definitely a cool alternative to
the database track at OSCON, because here we can do technical talks
liable to be comprehended only by other database geeks.
