So you've got a limit of 1GB on process address space ... that's
probably why it's burping on allocations of a couple hundred meg,
especially if you have a reasonably large shared_buffers setting.
You might as well be running a 32-bit build (in fact, a 32-bit
build could still do a lot better than that).
