For 7.4 I would like to add a function for importing float8 values into cube. But because the cube data type is variable length I am not sure what a good approach would be.
Currently this can be poorly done using text as an intermediate type. As far as I can tell functions can't take sets as arguments. Arrays seem to suffer from similar problems as the cube type, so that preloading an array with the output of a few calculations isn't particularly easy unless you use text as an intermediate type. One possibility would be to have a function that adds one dimension on to an existing cube. This could be used recursively to build up a cube with desired number of dimensions. It may not gain much in speed, but would be more accurrate without having to adjust extra_float_digits. Is there some better approach that I have overlooked? ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
