An extension just for COPY to/from parquet looks limited in
functionality. Shouldn't this be viewed as an FDW or Table AM support
for parquet or other formats? Of course the later is much larger in
scope compared to the first one. But there may already be efforts
underway [1]

I have not used it myself or worked with it.
