This is correct, I did not copy the executable to the production
machine.  I suspect I'll be copying the binary over to the production
system.

I moved the core file to the development machine where I built the new
binaries.  Ran gdb against this core file and the postgres binary on
this machine.  The core was not generated on the development machine.

I have not had any success in duplicating the failure on my development
environment.  I suspect it's because I can't generate the volume of
users.  The production system could well have 150-200 users at one time
and we get a core file generated about 3-4 times a week, generally on
the busiest days.
