I removed the item about the pg_stat_statements change from
release-11.sgml, as part of a sweep to delete items already committed
in 11.0; but actually we'd best keep it to ensure that people who've
pg_upgraded their databases will take the requisite action. Also make
said action more visible by making it into its own para. Noted by
Jonathan Katz.

In contrib/pg_stat_statements, disallow
the pg_read_all_stats role from
pg_read_all_stats is only meant to grant permission
to read statistics, not to change them, so this grant was incorrect.

To cause this change to take effect, run ALTER EXTENSION
pg_stat_statements UPDATE in each database
where pg_stat_statements has been installed.
