Log message:
    More infrastructure for btree compaction project.  Tree-traversal code
    now knows what to do upon hitting a dead page (in theory anyway, it's
    untested...).  Add a post-VACUUM-cleanup entry point for index AMs, to
    provide a place for dead-page scavenging to happen.
    Also, fix oversight that broke btpo_prev links in temporary indexes.
    initdb forced due to additions in pg_am.
