There are other (less technical) points.
The licence of PostgreSQL allowes to extend your service without asking some
IBM or someone else for additional licences. It is just convenient.
And if you have problems and probably can solve it for yourself: in PostgreSQL
you are allowed to fix it. Another point is the future. If you would like to
try out the new AMD-Hammer for example, you can recompile PostgreSQL for
yourself. But if IBM chooses not to support your future platform, you are
lost.
The other side is responsiblity. If you choose DB2 IBM is responsable for it.
What if some day your data get corrupted? IBM will help you (for money of
course, but they must). On PostgreSQL you are more or less on your own. There
is no so strong commercial support.
These points do not belong just to Sourceforge, but these are arguments for
choosing one database or the other.
