That seems suspicious. You sure you pointed gdb at the correct postgres
executable?

This is pretty obviously bogus, since ReleaseAndReadBuffer isn't in eval.c.
It might be that you will need to rebuild postgres with debugging
symbols before you will get a useful backtrace. I have noticed that on
some platforms, gdb's backtrace from a non-debug-enabled executable
is not just incomplete but flat-out wrong. This looks like it could
be one of those cases.
