The first two commits b0f18cb77, 30df93f69 are done as preliminary
work to "Add write-ahead logging support to hash indexes", so it seems

<!-- Author: Robert Haas <rhaas@postgresql.org> 2017-03-14 [c11453ce0] hash: Add write-ahead logging
support. --> <para> Add write-ahead logging support to hash indexes (Amit Kapila) </para>
