I am trying to write a function, and have written this :


        var_params_shootingstar := 




                       t1.status = TRUE,

                       AND    (




                                          z( pointn(
geometryn(d3.the_geom,1), 1) ) AS z

                                          FROM streets_3d d3

                                               WHERE d3.gid = t1.gid 

                                   ) / $v$ || var_rain_cm || $v$

                                  ) >= $v$ || var_ratio_car_rain || $v$


                        AND     ( 

                                   $v$ || var_ratio_cartype_rain || $v$ <=






       RAISE NOTICE 'Where clause : %',


Instead of $v$ I also tried $vps$ and ' . I also tried removing
quote_literal() to no avail.


My problem is that I get : NOTICE:  Where clause : <NULL> when I try to
execute the function. 


I tried changing it to  var_params_shootingstar :=  $v$ this is a test $v$
|| var_rain_cm || $v$ end of test $v$;

And this is the result I got : NOTICE:  Where clause :  this is a test 0 end
of test


BTW : var_params_shootingstar is declared as TEXT.


I know this is a very strange problem, hence why I am asking here, been
trying different things for more than an hour.


Any help is extremely appreciated.


Thanks and regards
