I think the solution is to use streamed blobs (from FDB documentation):

# Insertion:cur.execute("insert into blob_test values (?)", 
(StringIO('abcdef'),))

# Retrieval using the "file-like" methods of BlobReader:

cur.execute("select a from blob_test")cur.set_stream_blob('A') # Note the 
capital letter
readerA = cur.fetchone()[0]

value = readerA.read()
