[postgis-devel] estimated_extent() for PG<80

[strk at refractions.net]

I've implemented estimated_extent() for PG<80.
Note that in this case the histogram extent can be
more accurate (statistics for PG<80 always scan the whole table).

For standing up against patentability of software,

  Thank You, Poland!
