Create and exposequeryNamedWith

[yogsototh]

I missed that specific function because I couldn't put a type constraint (FromRow) in some typeclass.

Is there a reason this was not merged?

The previous maintainer went missing and I took over after your PR. I just saw your reminder. Is there any special reason not to have analogs like foldNamedWith? I think that well-defined analogs for the With should be defined. For that matter I wonder why there is queryWith but not foldWith. I think these matters should be handled together instead of in a piecewise manner, with the principle that the With and Named variants should be defined wherever reasonable.
