Comment:

 Having ST_AddMultiBand would be nice.  Being able to specify the
 properties of each new band effectively without going off the deep end in
 the function parameters may be difficult.  Maybe a variadic parameter of a
 new "band properties" type...

 My only question is the following...

 {{{
 ST_AddMultiBand(newrast, ST_Band(oldrast,ARRAY[1,4]) )
 }}}

 ST_Band returns a new raster of bands 1 and 4 of oldrast so calling
 ST_AddMultiBand confuses me.  Granted, I've been thinking that we need a
 function to copy a band from one existing raster to another existing
 raster... but that is getting off topic.
