Not sure if Postgres has something in the utils for that.
You can use backtrace() in glibc. Solaris 9 libc has printstack(). Not sure
what's available for Windows.

Is there any way to print out the stack trace of the current location?
I am looking for something like print_stack_trace(); that I can insert in

Currently, I am investigating the
