Changes:

.
* New upstream version.
.
* Tighten security restrictions within REFRESH MATERIALIZED VIEW
CONCURRENTLY (Heikki Linnakangas)
.
One step of a concurrent refresh command was run under weak security
restrictions. If a materialized view's owner could persuade a superuser
or other high-privileged user to perform a concurrent refresh on that
view, the view's owner could control code executed with the privileges
of the user running REFRESH. Fix things so that all user-determined code
is run as the view's owner, as expected.
.
The PostgreSQL Project thanks Pedro Gallegos for reporting this problem.
