pgsql: Fix dumping of security_barrier views with circular dependencies

Fix dumping of security_barrier views with circular dependencies.

If a view has circular dependencies, pg_dump splits it into a CREATE TABLE
and a CREATE RULE command to break the dependency loop. However, if the
view has reloptions, those options cannot be applied in the CREATE TABLE
command, because views and tables have different allowed reloptions so
CREATE TABLE would reject them. Instead apply the reloptions after the
CREATE RULE, using ALTER VIEW SET.
