Interesting. It looks like they have support in for PostGIS for their
latest version. Would be interesting to see what they are doing with that

Subject: Re: [postgis-users] Rasters
Paul.. it´s not a direct answer for your questions but...
could help to clarify somethings.
I know that terralib can store and manipulate raster data
in normal database (even mdb´s) and spatial database too.
http://terralib.org/ (All in English)
We could take a look to how terralib team implement raster objetcs inside
RDBMS, and see what could be used in PostGIS.
The basic class is "TeRaster"
These book explain more about that, but actualy just in portuguese, i heard
that some one was translating to
english, but i can´t remember who. But some exemples are
easy to understand (because all code is in English).
These chapter is about how they deal whit raster data.
Well.. i´m not from terralib team and probaly will don´t
know the ansewers of some questions that could apper, so if
you what you can talk with them at:
My 2$ . :-)
