I was suggesting that you, essentially, write your own SQL to have a materialized view, *not* use the PG materialized view system. In other words, the 'side-table' that you create would be *your* materialized view, but to PG, it'd just look like a regular table. You can't modify a PG materialized view. Thanks! Stephen
