What .Net orms or MicroOrms support async operations and PostgreSql

Question

What ORM's support async operations and postgresql ?

I prefer simple MicroOrms like Dapper and OrmLite because they seems to have great performance and they are really simple, but they do not support async operations as far as I can tell.

Maybe I am wrong, but isn't important to make all IO bound operations async to get the full benefits of say an async web service that needs to scale?

So what are the options regarding an MicroOrm with support for both async operations and Postgresql? I have just read about a new Orm called Insight.Data, but I am unsure whether it properly supports PostgreSql.

If you are using .NET 4.5, I wrote a fork of Dapper that adds async methods that internally call ExecuteReaderAsync. It is also available on NuGet. I haven't tested it with Postgresql but if Dapper works with it then my fork should as well.
