I hope not a religious war on my part. I am happy with both choices abstractly (and I am a big user of sqlite3 as well, which is excellent but not so much for multi-user update-heavy applications). My point (and this whole comment is certainly directed at Martin, who is the ongoing developer) is just that after installing many open-source projects that have database access, there seem to be a non-trivial number that don't support PostGres but do support MySQL, so it might be helpful to make that the pre-installed database.<br>
<br>As to Sameer's point that anything can be installed after the fact: that's true with a reliable connection. Having just spent several weeks in connectivity hell, I can assure you that trying to do "yum install" over a line that has frequent glitches is miserable, so it would be kind to try to make "most common" decisions in the base install. (And drupal, btw is one of those packages that supports both databases.)<br>
