Sounds cool. On the other hand, I think it's kind of too domain specific
task. So I wonder whether it could be generalized somehow so anyone
could write an extension that would export data in any format in a
friendly way.

For instance:

create extension export_to_gnuplot;
select * from data
\export_to_gnuplot | gnuplot ...
