WAL-log the extension of a new empty MV heap which is being populated.
This page with no tuples is used to distinguish an MV containing a
zero-row resultset of its backing query from an MV which has not
been populated by its backing query. Unless WAL-logged, recovery
and hot standby don't work correctly with what should be an empty
but scannable materialized view.
Fixes bugs reported by Fujii Masao in testing MVs on hot standby.
