Hi Marc,
Dear Koha-Devels,
during the Marseille Hackfest 2012 I started together with Stephane and
Christophe from BibLibre to add support for the PostgreSQL database.
The ultimate goal of this work is that Koha can run on a PostgreSQL
server as as good as it does now on a MySQL server.
This mostly boils down to removing the MySQLisms in the current code,
which I am currently doing. The collect-all-activity bug for this is
7365, it holds dependencies to the individual bugs like 7802, 7806 etc.
(more to come, obviously). There is also a wiki page
wiki.koha-community/wiki/PostgreSQL which I update frequently.
This work also means that you must not add new MySQLisms in new code.
And please be advised that adding MySQLisms in new code will fail in QA.
