But why is that hugely better than piping psql output to gzip?
The Unix philosophy is to use small chains of tools rather than put
everything into one big tool.
Thus, this is quite unlike inplace upgrade, which I agree would be great
(and where I would far rather see people spend their efforts), because
unlike for this "feature" there is no viable alternative.
