[pgpointcloud] Sorting a patch.

[David Serret Mayer]

I have no idea how to sort a patch. I have tried this but it says: ERROR:
column "x" does not exist

select pc_sort(( select pa from patches where id=14 ),   x );

Could somebody provide an example?

   1. Is sorting important performance wise for further queries?
   2. How do I sort "in place" a whole patch?

Thank you in advance
