Is wal_log_hints still not configurable ?

Environment

• Patroni version: 2.0.2
• PostgreSQL version: 11.5

Is there still a way to disable use_pg_rewind and setting wal_log_hints = off respectively ?

Thanks.

Yes, I looked through that one, I didn't find an explanation on the closure. I agree that not having wal_log_hints/checksums/rewind is a valid use case. I'm currently experiencing a serious performance degradation after switching from the stream replica to Patroni, checked the configs back and forth, the only difference is the wal_log_hints generating tons of WAL iops.

Would you recommend any workaround, what if I disable the rewind and apply a local patch ?

Thanks.
