When importing CSV data that is tab-separated, it's quite inconvenient to supply a tab literal on the command line to override the default separator (you need to press Ctrl-V, followed by Tab, which isn't well known).
It would be better if it was possible to supply something that looks like a tab literal, i.e. '\t', or something else like '<tab>', to reduce the complexity in supplying a tab separator.
Regardless of the approach, the way to supply a tab character should also be added to the documentation (or to the command line docs provided by the tool).
This should be done for both the map reduce bulk loader, and psql.
