commit 848b9f05ab283724dd063d936a92568c1fdf422b
Author: Heikki Linnakangas <heikki.linnakangas@iki.fi>
Date: Wed Apr 16 07:21:09 2014 +0000
First released in: 9.4.0, 8.4.22, 9.0.18, 9.1.14, 9.2.9, 9.3.5
Use correctly-sized buffer when zero-filling a WAL file.
I mixed up BLCKSZ and XLOG_BLCKSZ when I changed the way the buffer is
allocated a couple of weeks ago. With the default settings, they are both
8k, but they can be changed at compile-time.
