I think you misunderstand what is happening.  The parent postmaster
process is not restarting, because it did not crash.  The crash is
happening in a child process that is forked off by the postmaster to
service a particular connection.

No, we want a stack trace from the crash.  You could attach gdb to the
child process after forking and before you provoke the crash; or arrange
for a core dump file to be produced and gdb that.
