A PostgreSQL-compatible application needs a managed database optimized for demanding PostgreSQL workloads, including supported analytical acceleration features. Which approach best fits?

1. Evaluate AlloyDB for PostgreSQL.
2. Use an appropriate Memorystore cache with explicit expiry and consistency behavior.
3. Retain a compatible relational model unless the application and access patterns are redesigned.
4. Evaluate AlloyDB Omni and its supported deployment requirements.
