On this note, there has been a proposed (but as far as I know untested) patch to speed up this sort in a much simpler way, in this thread https://www.postgresql.org/message-id/CA%2BhUKGKztHEWm676csTFjYzortziWmOcf8HDss2Zr0muZ2xfEg%40mail.gmail.com where you may find this patch https://www.postgresql.org/message-id/attachment/120560/0007-Specialize-pagetable-sort-routines-in-tidbitmap.c.patch and see if it helps. -- John Naylor EDB: http://www.enterprisedb.com
