Although I've wanted this earlier, now that MySQL is completely (not just InnoDB anymore) under the thumb of Sun, and (without getting into a flamewar over the MySQL/Postgres rivalry) with the other advantages of Postgres, I'm also waiting for a Postgres solution to Drupal. Let's hope Drupal doesn't go down the Compiere path.
Maybe using PEAR DB to enable portability and use of not just Postgres but other databases as well? Write once, run everywhere?
Another <a href=http://www.linux.com/?module=comments&func=display&cid=1184597>request</a> , and more requests in the modules message boards for the same (Postgres) thing.
