Materialized view does not seem to work unless I specify the option "MATERIALIZED true", but this is not documented anywhere on the page. (By "doesn't work" I mean src command is executed every time.)
I want async materialization. The "TTL Snapshot Refresh" section is misleading because it is portrayed as an async alternative to using the "MATVIEW_TTL" option at the top of the page, but as far as I can tell they both do the same thing. The "lazy-invalidation" VDB property does what I want, but the property (from grepping the code) is actually "lazy-invalidate".
