You should be able to use 8.2 and above. I've been testing on 8.3 and
8,4.
(I think we may have scrapped support for 8.1 in 1.4 but can't remember)

Are you busy testing the new code? I hope you are!
Want a place in history? I'm looking for a few "testimonials"
for the
final release announcement when 1.4 comes out, so compare your
production queries on Pg1.3/G3.0 with Pg1.4/G3.1 and report back
on
how much faster things are.

PostGIS users,

performance improvements in PostGIS, prepared geometries

which have been brought over from JTS over the past
year.
What both these features have in common is that they
require GEOS 3.1.
We have begun a Release Candidate series for GEOS, and
now need
testing to ensure it is ready for full release.
In order to try these features, you will need.
- PostGIS SVN snap (aka 1.4):
http://postgis.refractions.net/download/postgis-1.4.0SVN.tar.gz
- GEOS 3.1RC2:
http://download.osgeo.org/geos/geos-3.1.0rc2.tar.bz2
First compile and install GEOS, then PostGIS.
The functions that have been sped up include:
ST_Union(geometry) aggregate
ST_Intersects()
ST_Contains()
ST_Within()
ST_Covers()
Thanks,
Paul
