looks like it won't work using psycopg2's named cursor implementation,
at least not without some patching. it seems like psycopg should fill
in cursor.description after it issues the DECLARE, but it doesn't. you
can do it using one normal (non-named) cursor in SA using the method
above, but it
cursor.description isn't available after the DECLARE (analogous to
conn.cursor(x)), but is available after a FETCH (analogous to a
cur.fetchXXX()). If you want to get rid of the buffering resultproxy,
you can do a FETCH ABSOLUTE 0 FROM cursor_name - that will make
cursor.description available,
