The cost of the partial query is paid at these times, so we can benefit from that over and over, especially in read-heavy situations (most situations are read-heavy in my experience). Create a materialized view within a postgres database; Connect to the postgres database with SQL Tools; Materialized view is not shown under tables or views subtree; Expected behavior Materialized views should show up under a tables or views subtree, whichever is more practical for the current pipeline but they should at least show up.
