dumping database privileges broken in 9.6

Do this:

CREATE DATABASE test1;
REVOKE CONNECT ON DATABASE test1 FROM PUBLIC;

Run pg_dumpall.

In 9.5, this produces

CREATE DATABASE test1 WITH TEMPLATE = template0 OWNER = peter;
REVOKE ALL ON DATABASE test1 FROM PUBLIC;
REVOKE ALL ON DATABASE test1 FROM peter;
GRANT ALL ON DATABASE test1 TO peter;
GRANT TEMPORARY ON DATABASE test1 TO PUBLIC;

In 9.6, this produces only

CREATE DATABASE test1 WITH TEMPLATE = template0 OWNER = peter;
GRANT TEMPORARY ON DATABASE test1 TO PUBLIC;
GRANT ALL ON DATABASE test1 TO peter;

Note that the REVOKE statements are missing.  This does not correctly 
recreate the original state.
