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.

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.
