   "abstract": "Multi-level data integrity checksums for PostgreSQL",
   "description": "pg_checksums provides checksum functions for PostgreSQL at six granularity levels (page, cell, tuple, table, index and database), each in a physical and a logical variant (cell level is logical only). Physical checksums detect storage corruption and change after VACUUM FULL, CLUSTER or REINDEX; logical checksums depend only on the data content and stay stable across physical reorganization. The implementation uses the FNV-1a 32-bit hash, supports parallel scans through the pg_checksums.workers GUC, and transparently aggregates partitioned tables.",
