Hi Acaymo, In some way, it is expected: the algorithm needs to loop on all the pixels for the interpolation, and this can be time consuming in case of large rasters, specially if you consider that st_invdistweight is a function implemented in PL/pgSQL.
Anyway, did you consider to split the raster in tiles, and run the interpolation on the single tiles? Hope this can help, Giuseppe.
