Comment:

 I realized after I committed the geography_interpolate tests that tests
 were already in place for these new functions in the geography.sql.  I was
 about to remove the tests I added, when berrie (32-bit failed with this)
 and gitlab 32-bit failed on this.

  gitlab 64-bit is also failing, but that looks to be a rounding difference
