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.
