PgQueryNarrative reads a PostgreSQL execution plan, proposes a bounded rewrite or index from the query's own parse tree, compares before and after, verifies the results match, and writes the evidence into a report.https://pgquerynarrative.vercel.app/https://pgquerynarrative.vercel.app/blog/test-postgresql-index-before-building-hypopg/https://pgquerynarrative.vercel.app/blog/test-postgresql-index-before-building-hypopg/Compare PostgreSQL index candidates with HypoPG, then measure the real index.
