If you remember with the SugarCRM 6.4 release, one of the big goals we had with the database refactor it was to make it easier for building out new database backends by only needing to change the code at the driver level itself. With this we added DB2 support to the Enterprise edition of Sugar, and also made a call to the community to build out new backends to help Sugar run on more and more databases.
One developer has taken that charge. Antonio Musarra is a freelance developer from Italy who has did a fork of Sugar on GitHub to add PostgreSQL support to it, only adding the new DB drivers and not having to make any core changes to the app. He is also providing us great feedback in the process, letting us know of any bugs along the way he is seeing to make sure the fork is successful.
With any community project like this, many wonder if this is something we’d be interesting in having the core Sugar application. Is Postgres something you’d use in Sugar, or do you have a client that would love to be able to use PostgreSQL instead of MySQL. Let us know in the comments and vote on this bug to show your interest and support.
