So, we tried AWS RDS Proxy for MySQL (well, actually AWS RDS Aurora MySQL), and we found that it did not improve our situation at all. It added latency, but no additional performance, and memory usage was unchanged.

The applications already had their own connection pooling functionality built-in, so AWS RDS Proxy didn’t buy us anything more beyond that.

I can’t speak for what this technology can do for situations where your application code does not already have connection pooling, or for cases regarding RDS Postgres.
