Ideallyonly the columns in the selected row should be visible, even better if there would be one column of that row per

Let me flesh out my need a little bit more. I have a need for a quick-and-dirty solution to paging through a postgresql
table.pspg almost fits that need but could be even better. Using pspg I can either: (1) view one table row in each pspg
terminalwindow row using the pspg flag to shorten columns, or (2) list as much of the table row in the pspg terminal
windowas fits. Depending on the size of the row, this could mean less than one table row or more than one table row.
To make it easier to view individual table rows in eg. pspg I would like to view exactly one table row, not more, and
ideallyeach column of that table row would use individual pspg terminal rows.
I hope that makes it clearer. Hoping this might be possible, either using pspg or other similar software. I am not
writingany application code.
