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? regards, tom lane
