Maybe somebody have an idea how to escape text string for use in hstore

During insert occurs error:

The same occurs with backslash:

Here is my very similar function:
CREATE OR REPLACE FUNCTION utility.archive_del_record() RETURNS trigger AS
$BODY$
DECLARE
tbl_name text := TG_TABLE_NAME || '_delete' ;
archive_row hstore := hstore(OLD.*);
user_name text := session_user;
BEGIN
EXECUTE 'INSERT INTO ' ||quote_ident(tbl_name) ||
'(record_fld, del_ts, del_user)'
|| ' VALUES('||quote_literal(archive_row)||', now(),' ||
quote_literal(user_name)||')';
RETURN OLD;
END;
$BODY$
