Postgres Materialized Views

An attempt at creating materialized views for Postgresql. I am not only attempting to add this grammar to the parser, since that would not be very interesting really. I would like to expand what can be done with views to include the use of views in queries where they are not even specified. I plan to do all this while avoiding painful data-duplication and maintaining the speed of access Postgres is known for.

Please see the wiki for more information and installation instructions.
