If I read this right, http://lkml.org/lkml/2007/2/9/275 even the
shared memory is counted many times (once per child) for the
parent process - even though it's (obviously) not copy-on-write
so the shared memory's unlikely to contribute to problems.
I wonder if postgres startup should write something (warning?
at least log?) in the log file if the OOM killer is enabled. I assume
most people who care deeply about their database dying would notice a
warning in log files; while most people who don't mind the OOM killer
also wouldn't be too bothered by extra noise in the file.
