I have a need to be able to page through a table one row at a time, possibly using pspg (or other tool) allowing me to move in either direction in the table one single row at a time. Ideally only the columns in the selected row should be visible, even better if there would be one column of that row per row in the terminal window but that would probably be wishing for too much.

Yeah, I was confused by the question. I originally thought you were
asking about pagination, and I have several blog entries about that:

but it then sounded like you were looking for a terminal-level API,
which kind of sounded like pspg, which you are using, but something much
more sophisticated.
