Comment (by jorgearevalo):

 Ok, I've reproduced the error. The first checking in the C SRF function
 rt_dump_as_wktpolygons is:


 {{{
 if ( (PG_NARGS() < 1 || PG_NARGS() > 2 )
 {
 elog(ERROR, "RASTER_dumpAsWKTPolygons requires 1 or 2 args\n");
 PG_RETURN_NULL();
 }
 }}}


 I've printed PG_NARGS() and it's a big number (16297). I don't know if
 it's related with the fact the raster, the first argument, must by
 detoasted with PG_DETOAST_DATUM(PG_GETARG_DATUM(0)), and it's considered
 like "a lot" of input arguments. Has sense?
