The traces include code from /usr/local/lib/libgrid.so and /usr/local/lib/libpcmsrv.so ... I don't know what those are, but I'm quite sure they are not invoked by a standard Postgres build. I also find it suggestive that they appear to have been written in C++ ... we've seen problems before from trying to link C++ code into the backend, because it tends to bring along its own incompatible ideas about how to do error recovery and memory management. regards, tom lane
