    CREATE INDEX ... INCLUDING (column[, ...])
    Teodor Sigaev authored 
    Now indexes (but only B-tree for now) can contain "extra" column(s) which
doesn't participate in index structure, they are just stored in leaf
tuples. It allows to use index only scan by using single index instead
of two or more indexes.
