Psycopg may raise a few other, more specialized, exceptions: currently
:exc:`~psycopg2.extensions.QueryCanceledError` and
:exc:`~psycopg2.extensions.TransactionRollbackError`. These exceptions are
not exposed by the main :mod:`!psycopg2` module but can be imported by the
:mod:`~psycopg2.extensions` module. All the additional exceptions are
subclasses of standard |DBAPI| exceptions, so trapping them specifically
is not required.
