   "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 data content: they exclude relation OIDs, heap TIDs and type OIDs, canonicalize enum, numeric, array, composite and range values, and do not require a primary key. Logical index checksums are derived from table data and the index definition, so they work for every access method. The implementation uses the FNV-1a 32-bit hash, supports parallel scans through the pg_checksums.workers GUC, and transparently aggregates partitioned tables and partitioned indexes. pg_checksums.strict makes database scans fail instead of skipping relations without a usable checksum.",
