Per Dimitri that's true of Event Triggers, but per my prior post on the
topic on this mailing list, it's not true of Materialized Views. As
I've said before, we get one, and only one, chance to promote a new
feature and that's when the feature first appears in a PostgreSQL
release *however incomplete it is*. If we try to promote it in a
successive release when it's "more finished", we will get zero traction
with the press. It's not news.

Aside from that, the MatView feature in the state it's in now is useful
to *me*, even if it's not useful to *you*. And I think that my
use-cases represent some hundreds or thousands of DBAs, so it's worth
promoting so that they will know about it.

Lets not let the perfect be the enemy of the good here.

No, I mean the ability to remaster using only streaming replication. As
Simon points out, this could be combined with fast failover into one
"feature" in our PR.

Ooooh! That got in?

Seems to me that becomes a feature once we have at least one example
useful worker. Any idea if someone is building one before 9.3.0?
