Hmm... I wonder if pg_reorg could be responsible for your problem? I
know it does a few tricky internal things.

Probably not very useful now.

It's an OS setup thing, but generally a crash will generate a core file
if it is allowed to. Use "ulimit -c unlimited" on linux in the shell
that starts postgresql and I think that will work. You can test it by
manually doing a "kill -11" on the pid of a backend process.

I meant a backtrace from the core file. If you don't have a core file,
then you won't have this information.
