Well, we're glad to have you to help. While most of us have a general idea
of what Firebird is, I don't think anyone on this list actively uses it.
When/if we do a grid/feature comparison, your help would be invaluable in
making that comparison with Firebird accurate.
Also keep in mind that this is an internal discussion list, so people do not
feel restricted to only extensively researched facts. There's a lot of
"throwing ideas out there".

MySQL is Open Source *released*, true, but it's not Open Source developed.
All code for MySQL goes through MySQL AB employees. Corporate ownership of
OSS projects is an established model ... Eclipse, OpenOffice.org, Sendmail,
etc. share this model with MySQL ... but it *does* make them significantly
different from us.
As a Firebird user, you should know the danger of corporate ownership, after
Borland "yanked back" the trademark, web resources, and their developers from
the project. MySQL AB could do the same thing, and unlike Firebird I'm not
sure a fork of MySQL, under a different name, would survive. Frankly, I'm
surprised that Firebird did and it's a testament to that project's user
community that it's still here. People may pooh-pooh this warning, but I
feel that the LGPL-->GPL fiasco with the MySQL libraries shows that MySQL AB,
as any company would, is willing to put their financial advatage over the
survival of their OSS project.
Such a "take-back" is not possible with PostgreSQL as nobody "owns" the
postgresql code, and what IP ownership exists is distributed among the core
team and contributors.

Good. Can you explain the Firebird license to me? I want to know it in case
I have a project that calls for Firebird ....

Sure. But we feel that versioning is better. As a professional MSSQL admin,
I strongly feel that versioning is much better than locking -- insoluable
deadlocks anyone?. Since we feel it's the better approach, why shouldn't we
trumpet it? The proponents of "transaction-spooling" databases are certainly
happy to champion their model.

Good. I may need it someday.

Seriously, that point was to point out the durability of PostgreSQL *as an
open source project*. One of the big questions I get from companies is "how
do I know that the PostgreSQL Project will be around in 3 years?" (my first
answer is, "How do you know that MSSQL server will be around in 3 years? MS
has killed projects before, and MSSQL is a money-loser ...")
But your point shows that we need to have 2 columns .... "age of software" and
"age of OSS project". For that matter, MySQL the software is about 2 years
older than MySQL-GPL.
