I am trying to find "islands", polygons in a (multi)polygon layer which
are not connected to any other polygons in the same layer. What I came
up with runs in a couple of seconds on a layer with ~1000 geometries,
and a couple of minutes on a layer with ~23,000 geometries, but I want

Hi,
Sorry for complicating things.

Sorry to be a little bit late in the discussion, but in my opinion, there
are really two sensible solutions:
1) Use the most simple and liberal (permissive) license. No license is not
an option, since it means copyright by default, and public domain is not a
good option due to specific issues

+1. If there was one true answer to the licensing question, this would be
it.

Oh, I prefer GPL, and in this case, since it's uncompiled code it probably
doesn't matter. I just know lots of people belly ache about the GPL, so
I'm trying to insert that perspective... . :)

+1 for GPL "version 2 or later"
Same license that applies to PostGIS.

How could we avoid a license discussion... :) . I think there are two
relevant points from the discussion:
1) It should be licensed such that it can go into core if such an option
for some or all functions reveals itself in the future
2) It should be flexible enough for wide reuse.
#1 precludes
I guess the fact that PL/pgSQL is not compiled and hence is open "by nature"
should have an incidence on the choice of the license. No?
I bend toward GPL in any case...

I knew we would fall into a license nightmare... So far we've got suggestions
for "No rights reserved", BSD, Creative Common Zero, GPL, LGPL, MIT...
Any of these license would make it hard to move a function from the Add-ons to
PostGIS core? That would be a good candidate for elimination.

Hello,
Did you try with a new raster
CREATE TABLE schema.data_raster_newval AS
SELECT rid, ST_SetValue(rast,1, geom, 100) AS RAST
FROM schema.data_raster, schema.data_vector
What is the result ?
Since you have only one tile, I don't think the intersect statement will really
improve performan
Dear Postgis list,
I have been struggling for a while with a seemingly simple raster
operation in postgis. I have a small number of quadratic polygons
arranged like a chessboard. The cells of this chessboard contain values
like elevation that I would like to write into a much larger raster
