Doc: correct thinko in pg_buffercache documentation.

tglsfdc · tglsfdc · commit 963ea55c34cc · 2020-02-28T11:30:49.000-05:00
Access to this module is granted to the pg_monitor role, not pg_read_all_stats. (Given the view's performance impact, it seems wise to be restrictive, so I think this was the correct decision --- and anyway it was clearly intentional.) Per bug #16279 from Philip Semanchuk.
