Sorry for not providing more context.

ATHENA:/var/pgsql/data # uname -a
Linux ATHENA 2.6.16.60-0.39.3-smp #1 SMP Mon May 11 11:46:34 UTC

VERSION = 10
PATCHLEVEL = 2

File system is xfs noatime,nobarrier for all data; OS is on ext3.  I
*think* the pg_xlog mirrored pair is hanging off the same
BBU-writeback controller as the big RAID, but I'd have to track down
the hardware tech to confirm, and he's out today.  System has 16
Xeon CPUs and 64 GB RAM.
