On Windows, you can use Stackwalk() or Stackwalk64() Win32 API. Several
years ago, for some software, I implemented a feature that outputs the stack
trace of a crashing process to its server log file.
It would be very nice if PostgreSQL outputs the stack trace of a crashing
postgres process in the server log. That eliminates the need for users in
many cases to send the huge core files to the support staff or to use the
debugger to get the stack trace. I've recently heard that MySQL has this
feature.
