There's still a lot of design work to do on the colors, the arrows, etc. But I think most of the information is there !
Of course there's probably many errors ! Especially it's hard to to tell if a project is dead or just inactive... So If you're a project leader and I marked that your software was halted, please forgive me ! I did my best to find information on the interweb but I'm sure I missed a few forks and some dates... If you have any correction to make please edit directly this page :
Overall I learned a lot doing this timeline ! Here's a few comments that came to my mind during the process :
* It's very easy to create a PostgreSQL fork * It's very hard to maintain a PostgreSQL fork * PG 8.0 killed the windows ports * PG 9.0 killed almost all the clustering projects
Well, 9.0 killed some of the replication projects. Postgres-XC probably did more than anything else to kill a lot of the clustering projects. Why use GridSQL when you can use Postgres-XC?
* What will PG 10.0 kill ? BI ? :) * Proprietary forks seem to be more resilient (not sure why)
Once I'll have cleaned this up, maybe I'll try to make a poster out of it.
