commit    5472ed3e9bc23eff0b4e457fe564ac667cb69441
Author:   Tom Lane <tgl@sss.pgh.pa.us>
Date:     Thu Sep 15 15:23:25 2016 +0000
First released in: 10.0, 9.6.0

    Make min_parallel_relation_size's default value platform-independent.
    
    The documentation states that the default value is 8MB, but this was
    only true at BLCKSZ = 8kB, because the default was hard-coded as 1024.
    Make the code match the docs by computing the default as 8MB/BLCKSZ.
    
    Oversight in commit 75be66464, noted pursuant to a gripe from Peter E.
