Huh, that's odd. One idea that comes to mind is that the core files
are frickin' large, for me typically around 3.5GB-4GB even for a
postmaster running with default shared memory sizes. (I don't know
why, although it seems to me they were less ridiculous a few years
ago.) Is it possible you're running out of space, or hitting a
quota of some sort?
