Perhaps you mean you want to quote of all strings? For that you use FORCE QUOTE.eg:
COPY (SELECT
name_first
name_last,
email,
company
FROM
clients
)
TO '/var/lib/pgsql/test1.csv' DELIMITER ','
csv HEADER QUOTE '"';FORCE QUOTE name_first, name_last, email, company;
Please RTFM--
Thanks! FORCE QUOTE was exactly what I needed.
