[Zope] Alternate storage for ZODB

Hi... I've seen here and there several articles about a replacement of the ZODB storage via an SQL backend, to store every Zope objects. Actually, I would like to test with a PostgreSQL storage, but I can't find any link anywhere to these kind of informations. Any link, advise or experimentation reports would be greatly appreciated...
