Today somebody has pointed me out that it could be interesting to be able to recovery up to a given LSN position. One argument behind that was to allow a maximum of things to recover up to the point where a relation block got corrupted by a specific record because of a broken segment. So that would be simply having recovery_target_lsn in recovery.conf similar to what we have now. Thoughts?
Sounds useful, if somewhat niche. I've needed that in the past, and just zeroed the WAL segment after the end of the target record. Not super user-friendly.
