Another updated version. I have changed the configuration setting to backtrace_functions plural, so that you can debug more than one location at once. I had originally wanted to do that but using existing functions like SplitIdentifierString() resulted in lots of complications with error handling (inside error handling!). So here I just hand-coded the list splitting. Seems simple enough. I think this patch is now good to go from my perspective. -- Peter Eisentraut http://www.2ndQuadrant.com/ PostgreSQL Development, 24x7 Support, Remote DBA, Training & Services
