Hello, I'm a new PostGis user so I might do some stupid questions. I have problem with all most every ST function.
I'f I type this query: *SELECT ST_BandIsNoData(rast) from mytable;* I get this result *ERROR: function st_bandisnodata(raster) does not exist* *LINE 1: SELECT ST_BandIsNoData(rast) from mytable;* * ^* *HINT: No function matches the given name and argument types. You might need to add explicit type casts.* Any suggestion how to solve this? I get the same error with many other functions. tnx Lorenzo
