SQL Query Diagnostics & Workload Optimization Platform

Diagnose PostGIS performance problems from a PostgreSQL EXPLAIN plan. Parses JSON and text EXPLAIN (ANALYZE, BUFFERS) output, runs ten spatial rules — missing GiST index, ST_Distance instead of ST_DWithin, loose bounding-box rechecks, un-indexed KNN, SRID transforms defeating the index — and prints an annotated tree, JSON or Markdown.
