You should be able to get that information from the .description member of
the cursor object. Have you checked it?
If not, you will have to use fetch the information from the
Postgres-specific tables, pg_class and pg_attribute. pg_class contains
information about your tables; when you fetch the class number for your
table, you can look up the columns in pg_attribute.
