*Something* is sending SIGINT to the postmaster --- it's simply not
possible to reach that elog call any other way.
How are you launching the postmaster? If from a terminal window, are
you sure it's entirely disconnected from the terminal's process group?
If not, typing control-C in that window could SIGINT the postmaster.
