pg_rewind (https://github.com/vmware/pg_rewind) is what you need.

But I think it has a problem regarding the hint bits which Robert Hass

You can still solve hint bit problem by enabling new checksum feature, But
you have to face consequences such as performance overhead.

You can find the discussion about that on following link:
