示例1: initMaterializedViews
/*
* Iterate catalog tables looking for tables that are materialized
* view sources. When found, construct a materialized view metadata
* object that connects the source and destination tables, and assign
* that object to the source table.
*
* Assumes all tables (sources and destinations) have been constructed.
* @param addAll Pass true to add all views. Pass false to only add new views.
