Ordinarily not, but perhaps you have a shell 'limit' setting in place
that prevents a corefile from being made? I think csh has such a
setting but I forget the details. Anyway, if postmaster is started from
a shell with any limit variables enabled, they will apply to the
backends too.
Or you might just not be looking in the right place. Backend crashes
produce corefiles in the database subdirectory, eg,
/usr/local/pgsql/data/base/MyDatabase/core
