Hm. Probably this is some unexpected problem with the
panic-on-fsync-failure change; although that still leaves some things
unexplained, because if fsync is failing for you now, why didn't it fail
before? Anyway, you might try experimenting with data_sync_retry,
instead of running with scissors by turning off fsync altogether.
See first item in the release notes:
https://www.postgresql.org/docs/11/release-11-2.html
Also, we'd quite like to hear more details; can you find any PANIC
messages in the server log?
