Hi there,

So the Ceilometer gate has been broken again by Nova today because of a
SQL bug in the placement API with PostgreSQL. This is the second time
that something like that happened: last November¹, we also reported a
bug in Nova wrt PostgreSQL.

Fortunately, Mehdi investigated and sent a fix:


So the issue is going to be resolved soon. I had hope this would not
happen again, but it seems Nova does not care about PostgreSQL since

I think I can understand that Nova does not want to support PostgreSQL
and therefore does not use it in the gate, however, I don't think it's a
rich idea to have other projects (e.g. Ceilometer) doing the gate check
for Nova.

My questions are simple and can be organized in a tree:

           Does Nova want to support PostgreSQL?
                 /                      \
               Yes                      No
               /                          \
   Why is there no gate?         Ok, we'll have to remove the 
                                 PostgreSQL job in Ceilometer
