The process ran smooth until copying edit notes:

Insert edit notes
DBD::Pg::db pg_putcopyend failed: ERROR: extra data after last expected column
CONTEXT: COPY edit_note, line 975742: "567,188,65154,"[<a href=""http://www.lifeinparis.com/dcd/dcddiscomain.php?&ANNEE=1993&BAND=DC"">http..." at ./edits.pl line 60.

Debug output for another case:

in: 566,65103,188,"""Thee"" is how it is on the album cover, not a typo",
out: 566,188,65103,"""Thee"" is how it is on the album cover, not a typo",

Its seems double quotes give it issues – this is an issue on how Text::CSV and Postgres' idea of CSV work.
