LEDAR Maps the Database You Inherited
A local, read-only PostgreSQL explainer that turns an unfamiliar running database into plain-language answers with explicit limits.
Field notes
The workflow begins by asking PostgreSQL what the connecting role can do, then refuses a superuser rather than relying on a promise of read-only behavior. A scan records constraints, relationships, row counts, and sizes, while inferred links are labeled as measured instead of presented as schema facts. Natural-language questions are constrained to areas selected from a product-built menu, and the homepage says each reported number comes from a query run against the user’s database.
