Author:   Teodor Sigaev <teodor@sigaev.ru>
Date:     Thu Apr 19 06:27:56 2018 +0000
First released in: 11.0

    Handle XLOG_BTREE_META_CLEANUP in btree_desc() and btree_identify()
    
    New WAL record XLOG_BTREE_META_CLEANUP introduced in 857f9c36 has no handling
    in btree_desc() and btree_identify().  This patch implements corresponding
    handling.
