Fabrízio and Tom, I know that you can use --variable="FETCH_COUNT=10000" from the psql command line, but internally that uses a CURSOR to batch the rows and [Redshift doesn't support CURSOR]( https://forums.aws.amazon.com/thread.jspa?threadID=122664&tstart=0) so it's not an option when using psql to download data from Redshift.
Pavel's idea of having a single row mode option to replace FETCH_COUNT is interesting, does anyone have any problems with that or alternative ideas?
