Mikael,
This crew of developers is not made up of kids. We don't know their
criteria for comparison of the two systems nor their experiences with them.
I suspect a lot of attitude comes from belief, not fact.

It may well be that the XRMS CRM/SFA application does not use any of these
features so their implementation in postgres and not mysql matters not to
them.
The most effective response, IMO, is for a group of talented and
interested postgres developers to download the code, look for the
MySQL-specific parts, translate them to PostgreSQL-acceptable syntax, and
release it as a fork of the original. For quite a few months I monitored the
mail list and saw many requests for help with installation, use, and actions
not working. There is a lot of room for improvement.
There is also ZohoCRM, which _is_ postgres based, but comes with version
8.0.something and no ability to use what we already have installed. That's
another poor development decision. Why would I -- or anyone else -- want to
intstall a second, older version of the dbms on their system, just to run a
single application.
As the head of a very small consulting company, I could benefit greatly
from one of these CRM tools to track our marketing/sales efforts. From all
I've seen xrms has the feature set I like the best, but I'll take any that
work. I don't have the time, financial resources, or postgres/php skills to
make the conversion on my own. I'm confident that I would not be the only
happy beneficiary of a postgres port.
