#5386: ST_MapAlgebra not respecting NULL nodatavalues

Comment (by robe):

 I also tried the original signature:


 {{{
 st_mapalgebraexpr(
         rast raster,
         band integer,
         pixeltype text,
         expression text,
         nodataval double precision DEFAULT NULL::double precision)
 }}}


  and this also seems to ignore the input nodataval even calling by named
 args


 {{{
 SELECT ST_BandNoDataValue(st_mapalgebraexpr(rast => rast, band => 1,
 pixeltype => NULL, expression => '[rast.val]*1'::text, nodataval => 1))
 FROM test_robe WHERE rid = 1 ;
 }}}
