Add simple materialized views with manual rebuilds

    XMLWordPrintableJSON

    Details

      Description

      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.
