Solutions Linux 2007 will r0x!
Devrim Gündüz and Magnus Hagander will be with us there, in the booth!
If you can afford it (see prices here), go the the track I lead called "SGBD" (means "RDBMS" in french), there will be a very nice presentation of what industrials did with PostgreSQL, see the complete program. There are other very interesting talks too, mostly about people that did migrate from proprietary to Open-Source databases. Enjoy!
