Comment(by dustymugs):

 So for various returnband:

 FIRST
 {{{
 ST_MapAlgebraExpr(rast1, band1, rast2, band2, '[rast1.val]',
 ST_BandPixelType(rast1, band1), extenttype, nodata2, nodata1, nodata1);
 }}}

 SECOND
 {{{
 ST_MapAlgebraExpr(rast1, band1, rast2, band2, '[rast2.val]',
 ST_BandPixelType(rast2, band2), extenttype, nodata2, nodata1, nodata2);
 }}}

 BOTH is FIRST and then SECOND
