The pyPgSQL, PySQLite and psycopg developers already agreed on an API
for the three projects (the newest versions implement this API):
If you want to add support for a new datatype for the DB-API module,
this data type should implement a __quote__ method that returns the
PySQLite and pyPgSQL already have a _quote method like the module-level
quote method Chris was arguing for. But it's currently only an
implementation detail, not part of the public APIs.
