This is probably the reason why "bt" is producing garbage:

So the core file is being truncated at 2GB, but the process image was a
little bit larger than that. You need to get a complete core file.
First thing I'd check is the "ulimit -c" setting that the postmaster is
being started under. I see that systemd is capturing the core dump,
so it could also be that there's some systemd configuration you need
to adjust ("man systemd-coredump" might help here).
