Thanks to everyone, Tom, Joe, Scott, I will be in touch today as I move through this.
Joe - if I need to have you log in for assistance, I am more than happy to make that happen.

There is some good information about using gdb with postgres here: http://wiki.postgresql.org/wiki/Getting_a_stack_trace_of_a_running_PostgreSQL_backend_on_Linux/BSD If you need a hand, I would be happy to help you through the debugging via phone or even log in remotely if you can allow it. Just contact me off-list if you want to pursue that. Note that I made a new PL/R release just a few weeks ago which fixed several known crash-bugs. In particular these two pop out at me: - Fix missing calls to UNPROTECT. - Don't try to free an array element value when the array element is NULL Joe -- Joe Conway credativ LLC: http://www.credativ.us Linux, PostgreSQL, and general Open Source Training, Service, Consulting, & 24x7 Support
