[postgis-users] creating a grid; transform error

[Salvatore Larosa]

Hi,
I'm trying the query and I get this:

ERROR: AddToPROJ4SRSCache: could not parse proj4 string '+proj=merc
+a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0
+units=m +nadgrids=@null
+no_defs' unknown projection id
SQL state: XX000

In spatial_ref_sys SELECT proj4text FROM spatial_ref_sys where srid =
900913

"+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0
+k=1.0 +units=m +nadgrids=@null +no_defs"

While the command cat /usr/share/proj/epsg | grep <900913>
return nothing!


Must I to add the string in EPSG file, too?
