Hm, something trying to elog before the setjmp's been executed?
Although I thought it was coded so that elog.c would just proc_exit
if there was noplace to longjmp to.  A mistake here might explain
the lack of any message in the postmaster log: if elog.c thinks it
should longjmp then it doesn't print the message first.
