Description
Currently PGHoard can only be configured to keep N basebackups. This should be improved to support various time-based scenarios, namely:
- keep basebackups to allow restoring to any point in X previous days
- long-term storing of older basebackups and enough WAL to keep them consistent, but not all the WAL for any PITR, supporting scenarios like allowing PITR for 14 days but also storing database snapshots for 8 last weeks and 6 last months
