As of c15d0a7521231c2cb71e664265e08d0ae514fc73 we have now 3 unit tests failing and 1 error due to lack of upgrade with PostgreSQL. This could be avoided if we were having PostgreSQL unit tests running by default as we've had for SVN.
I have filed so far (should there be dependency? I don't think so)
