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!
