Обсуждение: Stack trace

Hi all,<br /><br />Is there any way to print out the stack trace of the current location? <br /><br />I am looking for
somethinglike print_stack_trace(); that I can insert in arbitrary location in the code.<br /><br />Thank you,<br /><br

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.

Hm the backtrace() method does not give the line numbers of the methods in the stack trace, it only gives the hexadecimal offset. Is there anyway to retrieve the line numbers?

I have tried to Google it but to no avail.

Did you build with --enable-debug?
        regards, tom lane

Yes, I use --enable-debug as an option in configure

the binutil addr2line should do the trick.
