The only thing that seems rather bloated is the CacheMemoryContext,
which seems to be because the backend has cached info about several
thousand tables and indexes. Given that you say there's 9500 relations
in their schema, it's hard to believe that 9.2.4 is suddenly doing that
where 9.2.3 didn't. I'm wondering if they've done something else that
restricted the amount of memory available to a backend.
Maybe, since I'm running the same server and top shows a RES size a bit
large for idle sessions. Not so large than 9.2. Bellow is the actual
server top.
Just to be clear the below is for the 9.1.4 server you rolled backed to?
Yes.
