"It was discovered that pygresql, a PostgreSQL module for Python, was
missing a function to call PQescapeStringConn(). This is needed,
because PQescapeStringConn() honours the charset of the connection and
prevents insufficient escaping, when certain multibyte character
encodings are used. The new function is called pg_escape_string(),
which takes the database connection as a first argument. The old
function escape_string() has been preserved as well for backwards
compatibility.

Developers using these bindings are encouraged to adjust their code to
use the new function."
