> Currently the CSV COPY FROM command will not raise any error for non-existing
> paths. Instead only "0 rows imported" will be shown as result.
> As the COPY FROM command is often used for tutorials and getting started
> guides, I'd suggest to give a clear error message in case of a missing input
> file. Without such error it can be confusing for the user to see the command
> actually finish, without any clues why no rows have been imported.
