OK, that's fair. The SIG_DFL change I suggested will fix that problem
for SIGINT etc (except SIGQUIT, for which you should be *expecting*
a core file). I agree with Michael that we do not wish to change what
happens for an internal error; but external signals do not represent
a bug in PG, so forcing a PANIC for those seems unwarranted.
