[postgis-users] Mapserver connection to Postgis Raster

Mon Jun 6 07:37:32 PDT 2011

Hi,

No, the driver doesn't need an empty entry in raster_columns table. It
only checks for raster_columns' existence. This is one of the things
I'm going to delete from the driver's code.

Virginia, raster_columns table is used in PostGIS Raster extension, to
store metadata, but the driver doesn't use it. I don't think that's
the problem. Could you send me the SQL code for your raster table? The
code generated by raster2pgsql script.

Best regards,
Jorge
