Comment(by bnordgren):
I'm somewhat at a loss to understand why the band matters (other than to
compare with the nodata value, of course). So if the user elects to
"exclude_nodata_valueA", then the convex hull of the rastA is the shape
which needs to be tested for intersection with rastB, right? Essentially
what I'm getting at is that the only reason to supply a band index at all
is to tell the function which band contains the nodata value. If you want
to ignore the nodata value, I think you can omit the band index entirely.
I think this simplifies the above list to !#5, !#2 and
ST_Intersects(raster rastA, raster rastB) -> boolean
