Comment(by robe):

 Okay I think we have a small little problem here, which may or may not
 related.  you are right I'm not seeing this in the rtpostgis.sql.

 But how would one distinguish between this:

 {{{
 CREATE OR REPLACE FUNCTION st_mapalgebrafct(
         rast1 raster, band1 integer,
         rast2 raster, band2 integer,
         userfunction regprocedure,
         pixeltype text DEFAULT NULL, extenttype text DEFAULT
 'INTERSECTION',
         VARIADIC userargs text[] DEFAULT NULL
 )
 }}}

 and

 {{{
 CREATE OR REPLACE FUNCTION st_mapalgebrafct(
         rast1 raster, band1 integer,
         rast2 raster, band2 integer,
         userfunction regprocedure,
         VARIADIC userargs text[] DEFAULT NULL
 )
 }}}

 After all in the first - those extra texts could easily fall into VARIADIC
 loop since they are optional.  I think your first one the arguments should
 not  have defaults.
