I'm not sure why proj would require the NAD gridshift files for
converting a google (900913) projection to WGS84 long/lat. Do you get
any errors with this:
select st_X(wayLL), st_Y(wayLL)
from (
select ST_Transform('SRID=900913;POINT(653103 6.63036e+06 0)'::geometry,
4326) as wayLL
) as foo;
Hello,
thanks for your help.
Regarding your questions:
No, i don't use www.pgrpms.org, my system is openSuse 11.2, i installed their
postgresql, which is version 8.4.4.
Yes, i installed Proj4 from source. I have to say i'm not sure any more if i
installed Proj-datumgrid in the /nad subdirecto

Hello,
i have to say i don't know exactly, but placing that query i got:
gis=> select distinct st_srid(way) from planet_osm_point;
st_srid

Best regard
Also, what is the source SRID of your geometry column(s)? If you're
not sure, check the geometry_columns table, the constraints used in
the DDL, or try:
select distinct st_srid(way) from planet_osm_point;

It appears the grid shift files are missing. These are not necessarily
installed by default.
Are you using http://www.pgrpms.org/ ? Is proj-nad installed? Did you
install proj.4 from source? If so, did you get the ZIP files and put
them in the right place before configuring?

Hello,
(i accidentially posted this on the openstreetmap mailing list, but it
belongs here:)
I once got a hint on this mailing list to use a query like this to get the
lat/lon of the world capitals:
A)
select st_X(wayLL), st_Y(wayLL), name from (select
ST_AsText(ST_Transform(way,4326)) as way
