commit    7a567d9407deadeeff972ee39f42e39606121b05
Author:   Heikki Linnakangas <heikki.linnakangas@iki.fi>
Date:     Sat Dec 06 17:31:37 2008 +0000
First released in: 8.4.0

    MAPSIZE macro needs to use MAXALIGN(SizeOfPageHeaderData) instead of
    SizeOfPageHeaderData, like PageGetContents does. Per report by Pavan
    Deolasee.
