commit    14ca9abfbe4643408ad6ed3279f2f6366cafb3f1
Author:   Robert Haas <rhaas@postgresql.org>
Date:     Thu Feb 02 19:40:05 2017 +0000
First released in: 10.0

    Increase upper bound for bgwriter_lru_maxpages.
    
    There is no particularly good reason to limit this value to 1000,
    so increase the limit to INT_MAX / 2, the same limit we use for
    shared_buffers.  It's not clear how much practical effect larger
    settings will have, but there seems no harm in letting people try it.
    
    Jim Nasby, less a comment change I stripped out.
