Does psycopg not handle quoting for you? Almost all database interfaces
nowadays support something like:
result = myquery.execute('INSERT INTO foo (anInt,aDate,aText) VALUES
(?,?,?)', query_parameters);
The interface deals with quoting the "?" based on the type definitions
in the database.

Trying to quote things yourself is tricky. You'll need to handle
single-quotes in a string yourself - easy to get it wrong.
