My insert has a "returning clause," I don't think execute batch supports that.

I don't think so as you cannot pass in VALUES():
cur.execute('prepare pt(integer, varchar, boolean) AS INSERT INTO
prepare_test values ($1, $2, $3)')
execute_values(cur, 'EXECUTE pt(%s)', [(2, 'test', 'f'),])
SyntaxError: wrong number of parameters for prepared statement "pt"
DETAIL: Expected 3 parameters but got 1.
execute_batch works though:
execute_batch(cur, 'EXECUTE pt(%s, %s, %s)', [(2, 'test', 'f'), (3,
'dog', 't')])
