|
|
Reference these guidelines when:
|
|
- Writing SQL queries or designing schemas
|
|
- Implementing indexes or query optimization
|
|
- Reviewing database performance issues
|
|
- Configuring connection pooling or scaling
|
|
- Optimizing for Postgres-specific features
|
|
- Working with Row-Level Security (RLS)
|
|
|
|
## Rule Categories by Priority
|
|
|
|
| Priority | Category | Impact | Prefix |
|
|
|----------|----------|--------|--------|
|
|
| 1 | Query Performance | CRITICAL | `query-` |
|
|
| 2 | Connection Management | CRITICAL | `conn-` |
|
|
| 3 | Security & RLS | CRITICAL | `security-` |
|
|
| 4 | Schema Design | HIGH | `schema-` |

|
rules/query-missing-indexes.md
|
|
rules/schema-partial-indexes.md
|
|
rules/_sections.md
|
|
```
|
|
|
|
Each rule file contains:
|
|
- Brief explanation of why it matters
|
|
- Incorrect SQL example with explanation
|
|
- Correct SQL example with explanation
|
|
- Optional EXPLAIN output or metrics
|
|
- Additional context and references
|
