You didn't say anything that changed my opinion: it doesn't feel like
a TRUNCATE to me.  It's not changing the object to a different but
entirely valid state, which is what TRUNCATE does.

Peter claimed upthread that REFRESH is a subcommand of ALTER MATERIALIZE
VIEW and that this operation should be another one.  That sounds pretty
reasonable from here.
