Hi I finished work on pspg.
https://github.com/okbob/pspg Now it has special features like rows or block selection by mouse, and export related data to file or to clipboard in csv or tsv or insert formats. Some basic features like sorting data per selected columns are possible too. I hope this tool will serve well, and so work with Postgres (or other supported databases) in the terminal will be more comfortable and more efficient. Regards Pavel Stehule
