There's nowhere near enough information in this report for anyone to
help you. Please see

https://wiki.postgresql.org/wiki/Guide_to_reporting_problems

and

https://www.postgresql.org/docs/11/bug-reporting.html

for some advice about what to put in a useful trouble report.
Since you're getting crashes, we'd probably also wish to see
a stack trace,
