I think that's sensible. I've had variable results with glibc's backtrace(), especially on older platforms and/or with external debuginfo, but it's much better than nothing. It's often not feasible to get someone to install gdb and run commands on their production systems - they can be isolated and firewalled or hobbled by painful change policies. Something basic built-in to postgres, even if basic, is likely to come in very handy.
