[postgis-users] Again: ERROR: function 60821C60 returned NULL

[Obe, Regina]

Just to add to what Mark said.  I had this issue when switching over
from 8.1 to 8.2. It was a problem with the GEOS library interaction with
8.2 which I think was fixed with Geos 3.0.0rc4 and above (there might
have been a slightly lower version that fixed it.)

If you are running 8.2 with Geos 2.3 or something like that, then you
will get the below error you describe.  This problem did not occur with
Geos 2.3 and below against 8.1.

Thanks,
Regina

Hi Robert,

Can you confirm which version of PostGIS you are using (SELECT
postgis_full_version())? I tried the following on a PostgreSQL
8.1/PostGIS 1.1.6 installation here and it worked for me:


CREATE TABLE test AS SELECT MakePoint(random(), random()) AS the_geom
FROM generate_series(1, 10000);
UPDATE test SET the_geom = GeomFromText('POINT(0.0 0.0)', 4326) WHERE
the_geom IS NULL;
CREATE INDEX test_index ON test USING gist (the_geom);


Can you provide a complete SQL script similar to above that will
reproduce the error on your system?


Many thanks,

Mark.
