commit messages:
commit 17fa4c321ccf9693de406faffe6b235e949aa25f
Author: Robert Haas <rh...@postgresql.org>

commit 4c641d994e19676ef2fec574d52d2156ffc2b3ce
Author: Robert Haas <rh...@postgresql.org>
Date: Thu Jun 6 10:14:46 2013 -0400
Backport log_newpage_buffer.
Andres' fix for XLOG_HEAP2_VISIBLE on unitialized pages requires
this.
