Log message:
    The attached patch defines functions for getting distances between
    points on the surface of the earth and locating points within a
    specified distance using an index based on the contrib/cube package. The
    new functions are all of language type sql. A couple of bugs in the old
    earthdistance function based on the point datatype are fixed. A
    regression test has been added for both sets of functions. The README
    file has been updated to include documentation on the new stuff. There
    are comments about how this package is also useful for Astronomers.
