Reading binary data from Postgres 9 - Mailing list psycopg

Hi list,

I am storing a NumPy array in binary form in Postgres with:

import numpy as np

...

my_array = np.array(data_list, np.float32)

cur.execute("insert into my_table values (%s)", (psycopg2.Binary(my_array),))

I've confirmed that this works fine. However when I query this binary data from the database I am having trouble deserializing/getting it back into a NumPy array. The result comes back as a read-only buffer. Does psycopg2 have an opposite of Binary to handle this?

Thanks.
