committed

Fix failure to follow the directions when "init" fork was added.

Specifically this commit updates forkname_to_number() so that the HINTmessage includes "init" fork, and also adds the description of "init" forkinto pg_relation_size() document.This is a part of the commit2d00190which has fixed the same oversight in master and 9.4. Back-patch to9.1 where "init" fork was added.
