Best Practices (grab-and-go)

When using PostgreSQL with Java, follow these best practices:

1. **Use Connection Pooling**: Always use a connection pooler like PgBouncer to manage database connections efficiently.

1. **Environment Variables**: Store your database credentials in environment variables, never commit them to version control.

1. **Migrations**: Use a migration tool to manage your database schema changes.

1. **Error Handling**: Implement proper error handling for database operations.

1. **Monitoring**: Set up monitoring to track database performance and health.
