Adrien Di Mascio <Adrien.DiMascio@logilab.fr> [Wed, 03 Dec 2014 16:29:16 +0100] rev 10125
[server] add a db-namespace option in source definition (closes #1631339)
"namespace" is preferred to the postgresql term "schema" to try and
avoid confusion with cubicweb's schema.
cubicweb now depends on logilab-database >= 1.13.0
