Bruce Momjian 4c1383efd1 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. Bruno Wolff III		2002-11-08 20:20:22 +00:00
