Committed with one minor modification: I moved the boolean flag to be
near the other booleans rather than at the end. Thank you.

Committed, thank you.

I'm not sure the changes in intorel_startup() are correct. I tried
adding an Assert(into->viewQuery == NULL), and it fails because there's
another path I did not consider: "EXPLAIN ANALYZE CREATE MATERIALIZED
VIEW ...", which does not go through ExecCreateTableAs() but does go
through CreateIntoRelDestReceiver().

See:

Should we refactor a bit and try to make EXPLAIN use the same code
paths?
