## Problem See #2592 ## Summary of changes Compresses the results of initdb into a .tar.zst file and uploads them to S3, to enable usage in recovery from lsn. Generations should not be involved I think because we do this only once at the very beginning of a timeline. --------- Co-authored-by: Joonas Koivunen <joonas@neon.tech>
