I'm using the Ubuntu PostgresSQL 9.6.3 from this repo:
deb http://apt.postgresql.org/pub/repos/apt/ xenial-pgdg main
It looks like there is a "-dbg" package available:
postgresql-9.6-dbg - debug symbols for postgresql-9.6
I'll give that a try when I get the restart opportunity.

You would need to recompile (with --enable-debug added to configure
switches) if they're not there already. But if you used somebody's
packaging rather than a homebrew build, you can probably get the
symbols installed without doing your own build.

You should still be able to get a stack trace out of it, but the trace
would be much more informative with debug symbols. See
