In Linux, yes. Not sure about other OSes.
You can turn off the dumping of shared memory with some unusably
unfriendly bitwise arithmetic using the "coredump_filter" file in /proc
for the process. (It's inherited by children, so you can just set it
once for postmaster at server start time).
Yes Linux. This is very helpful, thanks. A follow-up question - will it take postgres a really long time to crash (and hopefully recover) if I have say 1T of RAM because it has to write that all out to a core file first?
Thanks,
Jeremy
