I would like to enable Performance Insights for my RDS Postgresql cluster but it doesn't seem to be possible.

Reproduction Steps

DatabaseInstanceProps has a key enablePerformanceInsights but DatabaseClusterProps does not have that key. Also the instanceProps contained inside DatabaseClusterProps is InstanceProps type and does not have the enablePerformanceInsights key either.

Environment

• CLI Version : 1.18.0
• Framework Version: 1.18.0
• OS : Ubuntu
• Language : Typescript
