Hi, I am trying to write a PL/pgsql function that will take a CUBE
variable (which will be a 1D point) and a double precision variable.
If the input CUBE is defined as
'(x,y,z)'::cube
the function would then return a CUBE value of the form
'(x+R,y+R,z+R),(x-R,y-R,z-R)'::cube
where R is the second argument.
The problem I'm having is to actually add R to the individual
components of the CUBE variable. I can't cast CUBE to float[] and I
don't see anyway to get at the individual components of the CUBE.
Any pointers would be appreciated.
