There's some accumulated wisdom at
https://wiki.postgresql.org/wiki/Generating_a_stack_trace_of_a_PostgreSQL_backend
I'd suggest that before worrying about that, you should install 12.1
(official release is tomorrow) and see if the crashes go away. There's
not much info in this report, but it could match any of several
already-fixed bugs.
