Database Dependency AnalysisMap PostgreSQL foreign-key dependencies, depth, coupling, and cycles from SQL DDL.SchemaIQ builds a foreign-key dependency graph from your PostgreSQL DDL and reports the structure that governs migration ordering and blast radius: dependency depth per table, fan-in and fan-out coupling, and circular foreign-key dependencies detected via strongly-connected-component analysis.

Dependency depth for migration ordering

Fan-in / fan-out coupling for impact analysis

Circular dependency detection (self-references excluded)
