[postgis-users] ST_Slope

[JamesH]

"Make sure st_slope(rast raster, band integer, pixeltype text) exsit as a
function."

When running the query above, ST_Slope:

'ERROR: function st_slope(raster, integer, unknown) does not exist, No
function matches the given name and argument types. You might need to add
explicit type casts.'

Is there a way to remedy this? There doesn't seem to be a clear answer
anywhere.

Regards,
James
