PostgreSQL reporting query
Load a PostgreSQL reporting query that benefits from join-strategy, row-estimate, buffer, and index review.
PostgreSQL diagnostics
- Use plain EXPLAIN for estimates without execution.
- Use EXPLAIN (ANALYZE, BUFFERS, FORMAT JSON) only when execution is safe.
- For writes, use staging or a rollback transaction before collecting actual execution diagnostics.
- pg_stats excerpts and existing index definitions improve planner advice.
Privacy and review notes
- SQLito flags likely planner issues; it cannot know production workload without context.
- Redact sensitive literals and proprietary schema details.
- Validate index suggestions against write volume, bloat, and maintenance cost.
PostgreSQL optimizer FAQ
Should I paste EXPLAIN ANALYZE for PostgreSQL?
Only when executing the statement is safe. Plain EXPLAIN is safer for writes and production-sensitive queries.
Can SQLito detect stale PostgreSQL statistics?
SQLito can flag signs of row-estimate mismatch when you paste plan and statistics context.
