commit    2ac1b2b175ea5456516e59fe2b53a1e0578a5dbd
Author:   Andres Freund <andres@anarazel.de>
Date:     Tue Mar 26 02:02:36 2019 +0000

    Remove heap_hot_search().
    
    After 71bdc99d0d7, "tableam: Add helper for indexes to check if a
    corresponding table tuples exist." there's no in-core user left. As
    there's unlikely to be an external user, and such an external user
    could easily be adjusted to use table_index_fetch_tuple_check(),
    remove heap_hot_search().
    
    Per complaint from Peter Geoghegan
