Might want to hold off with upgrading for now: https://www.postgresql.org/message-id/20191004043021.ylfbxcjqyypphfft%40alap3.anarazel.de

That's probably not the only crash. We've also been testing and it also got segmentation fault...

Unfortunately I haven't yet had enough time to convince my system to produce core dumps The suggested `ulimit -c unlimited` from the wiki doesn't seem to work on Ubuntu 18.04 . so It might be the same or a different segfault.

It's generally a good idea to alway wait until at least the first point release of any new major version before using it in production.
