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.
