Copying csv from database into a new table

I understand that postgres can copy a csv file from the filesystem into a table like this:

COPY my_table
FROM '/home/xxx/test.csv' 
DELIMITER ',' 
CSV HEADER;

I am wondering whether i can load a csv file that is stored as a bytea in another table ? Maybe something like:

COPY my_table
FROM (select my_csv_bytea from my_csv where id = 1)
DELIMITER ',' 
CSV HEADER;

No as bytea is not CSV. You would have to extract the bytea field and convert it into its CSV form and then you could load it into the table.
