PDU – Open-source PostgreSQL data rescue tool

I built this tool after dealing with several PostgreSQL incidents where the instance could not start and logical backups were unavailable. PDU is a read-only, last-resort recovery utility that extracts data directly from PostgreSQL data files. It’s fully open source, and I’m looking for feedback from people who have dealt with similar situations.
