Informix 9 was not a fork but a re-write of OR features added into the regular informix line.

PostgresForest is a fork of the JDBC driver, not from the backend code. ------元のメッセージ------ 送信者 : Tatsuo Ishii To: josh@agliodbs.com Cc:pgsql-advocacy@postgresql.org Cc:satoshi.nagayasu@gmail.com 件名: Re: [pgsql-advocacy] List of PostgreSQL Forks 送信: 2009/9/30 9:26 AM > All, > > Time for me to update this for a presentation at West.

Guys, Your idea of calling PostGIS a sort of fork seems a little odd. Isn't' that like calling any GPL software you use within your database a fork. PostGIS doesn't even do anything by itself. On a side note -- I would like to say there are other reasons PostGIS is not included in the PostgreSQL core besides the GPL license. We had discussed this a while back and even if we were to go BSD, we would not want to be included in the core because it would tie our release cycle too closely to the PostgreSQL release cycle and our PostGIS versions to a PostgreSQL specific version. As a community we like our freedom of releasing when we feel it is necessary to do so without having to worry so much about what the PostgreSQL side of the fence is doing. This may change as we mature, but that's the way it stands. Paul, Mark and Kevin can correct me if I am wrong in my statements.

It's basically a very, very, very smart pgpool.

Yes, strange definition. PostGIS is an add-on to PostgreSQL that uses
the extensions points PostgreSQL defines. It's not a modified copy of
PostgreSQL (a fork) and never was, it's always been built as an add-
on, using the ./contrib tree as a model.

Hi, Joshua D. Drake wrote: > PostGIS is not a fork. Not sure where that idea comes from. Neither do I personally consider Postgres-R a fork. I still think of it as a (rather huge) patch, a bit like SE-PostgreSQL. However, it clearly depends on your definition of what a "fork" is. Maybe "based on Postgres" or similar would better describe the list (and allow even more projects to be named)? Regards Markus Wanner

ISTR years back PostGIS was distributed as a complete bundle, with code
changes and under the GPL, which in most cases would qualify it as a fork; the
distribution method being important here. Certainly it would be enough to
confuse people.
BTW, if there is any possibility of it, I'd really love to see you guys
relicense under the BSD. There are a lot of positive upsides that would come
from a move like that.
