From ac2063ade566deb03e72e3da52cf472e125708b7 Mon Sep 17 00:00:00 2001 From: Robert Haas Date: Mon, 31 Mar 2014 13:06:26 -0400 Subject: [PATCH] Count buffers dirtied due to hints in pgBufferUsage.shared_blks_dirtied. Previously, such buffers weren't counted, with the possible result that EXPLAIN (BUFFERS) and pg_stat_statements would understate the true number of blocks dirtied by an SQL statement. Back-patch to 9.2, where this counter was introduced.
