Possible F/OSS project at my school district

[Erik Bixby]

My administration is considering moving our student information system
to Coldfusion MX 6.1 on top of Linux.  They have some questions they
would like answered before we choose a direction.

1) PostGRESQL versus MySQL - does anybody have any experience with
either and Coldfusion?  Good, bad or otherwise, they want to know if
there are going to be any advantages to one versus the other.  As far
as I know, PostGRESQL has more features that may be of value at some
point down the road, while MySQL is optimized for speed.  Apparently,
Coldfusion comes with a MySQL connector.  It may also come with a
PostGRESQL connector, and probably does, but the decision maker with
whom I just had a conversation wasn't sure.

2) Coldfusion MX 6.1 - does anybody have any experience with
Coldfusion on top of Linux, good, bad or otherwise?

3) Distribution choice - would anyone have any recommendations as far
as a particular distribution that would be best suited for what we're
planning on doing?

I apologize, in advance, for anything that may be redundant and/or
annoying.  I am just the network guy, asking on the big-whig's behalf.
 :)  I have a great deal of familiarity with computer networks and
operating systems.  But, my web-app and database fu is a little weak.=20
So, I was unable to provide him with definitive answers...  Also,
don't hesitate to ask for clarification on anything, if you need more
information.  Thank you all, in advance, for your input.
