I'd encourage you to consider submitting this to a commitfest to get
feedback on it, as a proper patch to add such a utlity to PG and which
we could use in our documentation instead of saying "cp", which is
pretty terrible.

Then again, as David mentioned, there are already utilities which do
this properly, even if they're not included in core today.

Thanks!
