[postgis-users] Changing band pixel type

[George Washington]

Hi, I imported a raster image in postgis 2.0 (Win 7) and it shows a pixel type of 32BF, an overkill for my needs.Is there a way of changing the pixel type to, say, 8BUI or 16BUI? I found st_bandpixeltype to access the type, but not yet a way to set it.Many thanks
