Are you saying that it *did* dump core, or that it *didn't*?  It's
possible that your coredumpsize resource limit prevented a core
dump from happening at all.  If you're playing with the development
code than it would be a good idea to set that limit so that you do
get core dumps.  Configuring with --enable-debug and --enable-cassert
would also be useful, if you aren't doing so already.

...but unfortunate for finding out what was happening :-(

Had you stopped and restarted the postmaster before the reboot?
That is, was the reboot really necessary to "fix" the problem?
Had you run "make install" while the postmaster was still running?
I haven't tested whether that could cause a problem, but I wonder
if that's possible.
