Paste SQL to get your schema grade
Missing primary keys, unindexed foreign keys, naming drift. The analyzer checks your schema and grades it in seconds. Nothing leaves your browser.
What the analyzer checks
- Primary keys on every table. Missing keys break identity and replication
- Foreign key indexes: Postgres does not auto-index FK columns, unindexed joins are slow
- Nullable foreign keys: usually a design smell unless the relation is optional
- Naming consistency: mixed snake_case and camelCase across tables
- Table shape: unusually wide tables and missing audit columns
