Hm, please see if you can get a stack trace:
https://wiki.postgresql.org/wiki/Generating_a_stack_trace_of_a_PostgreSQL_backend
Also try to figure out what query(s) are causing the crash.
(It's unlikely that the postmaster log doesn't provide more
information than you've shared here.)

Core dumps are unlikely to help anyone else; they are too
machine-specific. Not to mention that they might contain
sensitive data. You'll need to examine them yourself.
