 [wiki:WKTRaster/PlanningAndFunding roadmap]

 As stated in the comment 7 of the Specification Comments following the
 Code Sprint in
 http://trac.osgeo.org/postgis/wiki/WKTRaster/SpecificationWorking01, we
 should prefer the option of adding a band parameter to every function
 working on a single band like ST_AsTIFF(). In all these cases, if the band
 parameter is omitted, the function should work on the first band.

 ST_Band() is nevertheless a must have function for future release.
