975a7ada42 StorageMaterializedView: allow CREATE MATERIALIZED VIEW x TO y 
This allows creation of materialized views without inner tables,
using an existing table for materialized rows instead.
This is useful for cases when you want to detach the materializing
view, but keep the already materialized data readable, especially
when the inner table is replicated.
