I would like to enrich my stream with database calls as documented at:

https://ci.apache.org/projects/flink/flink-docs-release-1.11/dev/stream/operators/asyncio.html

What async database library does the asyncio code example use? It references a class called "DatabaseClient".

Additionally, does anybody know any async database libraries that work with PostgreSQL that they could recommend?
