[GENERAL] pg_rewind - enable wal_log_hints or data-checksums

Hi

In the PostgreSQL documentation for pg_rewind:

pg_rewind requires that the target server either has the wal_log_hints option enabled in postgresql.conf or data checksums enabled when the cluster was initialized with initdb.

What is the difference between the two options?

What are the advantages and disadvantages between the two?

Which one is the the preferred option?

Thanks

Regards

Dylan
