Yes. This change on CREATE INDEX was introduced by 2af07e2f7 together with
other commands, but it was missed to be mentioned in the commit message
although the description was added to the documentation.

The change on CEATE MATERIALIZED VIEW was introduced by a separate commit
b4da732fd, since which the REFRESH logic is used when creating a matview.
Should we add here a link to that commit, too?
