tomevault-io PostgreSQL Code Review
Quick Reference
| Issue Type | Reference |
|---|---|
| Missing indexes, wrong index type, query performance | references/indexes.md |
| JSONB queries, operators, GIN indexes | references/jsonb.md |
| Connection leaks, pool configuration, timeouts | references/connections.md |
| Isolation levels, deadlocks, advisory locks | references/transactions.md |
Review Checklist
- WHERE/JOIN columns have appropriate indexes
- Composite indexes match query patterns (column order matters)
- JSONB columns use GIN indexes when queried
- Using proper JSONB operators (
->,->>,@>,?) - Connection pool configured with appropriate limits
- Connections properly released (context managers, try/finally)
- Appropriate transaction isolation level for use case
- No long-running transactions holding locks
- Advisory locks used for application-level coordination
- Queries use parameterized statements (no SQL injection)
When to Load References
- Reviewing SELECT queries with WHERE/JOIN → indexes.md
- Reviewing JSONB columns or JSON operations → jsonb.md
- Reviewing database connection code → connections.md
- Reviewing BEGIN/COMMIT or concurrent updates → transactions.md
Review Questions
- Will this query use an index or perform a sequential scan?
- Are JSONB operations using appropriate operators and indexes?
- Are database connections properly managed and released?
- Is the transaction isolation level appropriate for this operation?
- Could this cause deadlocks or long-running locks?
