Waiting for 9.4 – WITH CHECK OPTION support for auto-updatable VIEWs

On 18th of July, Stephen Frost committed patch:

WITH CHECK OPTION support for auto-updatable VIEWs
 
For simple views which are automatically updatable, this patch allows
the user to specify what level of checking should be done on records
being inserted or updated.  For 'LOCAL CHECK', new tuples are validated
against the conditionals of the view they are being inserted into, while
for 'CASCADED CHECK' the new tuples are validated against the
conditionals for all views involved (from the top down).
 
This option is part of the SQL specification.

relation.  This will be addressed separately.
