   "description": "ProvSQL is a PostgreSQL extension that adds (m-)semiring provenance and uncertainty management. It transparently rewrites SQL queries to track how each result depends on input tuples, then evaluates the provenance in any user-chosen semiring -- Boolean reachability, counting, probability, Shapley values, where-provenance, data-modification tracking, and more. The source is split between sql/provsql.common.sql (the primary file, shown in the Source view on this page, for all supported PostgreSQL versions) and sql/provsql.14.sql (additional objects requiring PostgreSQL 14 or later: data-modification tracking and temporal validity ranges). The full source is always available from the linked repository.",
