Seems like a pretty good overview, but I'm not surprised at all that in the end it's COPY TO/FROM that won out by a good margin. Listing all the columns in order seems a bit superfluous and error prone, though. I'd recommend creating the list of columns to be inserted (or copied; copy_from has a 'columns' arg) and slicing the input hash with the same list (dict comprehension in Py).
