From a user standpoint this was mostly how I use COPY. Someone requests a report that they can manipulate in $SPREADSHEET. I write a query, place it inside a “COPY” statement with FORMAT CSV, HEADER TRUE, save to file, and deliver. > Another thought: Isn't CSV just the same as unaligned output plus some > quoting?

This makes a lot of sense. I’ve also generated CSV files using a combination of:
\f , \a \o file.csv
and then running the query, but if any of the fields contained a “,” if would inevitably break in $SPREADSHEET.
unfortunately, most used CSV separator in Czech Repuplic is ; due MS Excel settings for CR
