> This patch is a start at implementing simple views. It doesn't have enough
> testing yet (e.g. there's no negative testing). And I know it fails in the
> partitioned case. I suspect things like security and locking don't work
> properly yet either. But I'm posting it as a starting point.
> In this initial patch I'm just handling simple materialized views with manual
> rebuilds. In later JIRAs we can add features such as allowing the optimizer
> to rewrite queries to use materialized views rather than tables named in the
> queries, giving the optimizer the ability to determine when a materialized
> view is stale, etc.
> Also, I didn't rebase this patch against trunk after the migration from
> svn->git so it may not apply cleanly.
