Patrones de base de datos PostgreSQL para optimización de consultas, diseño de esquemas, indexación y seguridad. Basado en las buenas prácticas de Supabase.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

### Tabla de Índices
| Patrón de Consulta | Tipo de Índice | Ejemplo |
|-------------------|----------------|---------|
| `WHERE col = value` | B-tree (por defecto) | `CREATE INDEX idx ON t (col)` |
| `WHERE col > value` | B-tree | `CREATE INDEX idx ON t (col)` |
| `WHERE a = x AND b > y` | Compuesto | `CREATE INDEX idx ON t (a, b)` |
| `WHERE jsonb @> '{}'` | GIN | `CREATE INDEX idx ON t USING gin (col)` |
| `WHERE tsv @@ query` | GIN | `CREATE INDEX idx ON t USING gin (col)` |
| Rangos de series temporales | BRIN | `CREATE INDEX idx ON t USING brin (col)` |
### Referencia Rápida de Tipos de Datos
| Caso de Uso | Tipo Correcto | Evitar |
|-------------|--------------|--------|

How to install
mdr add affaan-m/ecc/postgres-patterns@sha256:e9c6bfe2bebc2998The line at the top of this page pins the label git:20260607.ac0f11c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
