if you're inserting DEFAULT into the cadc_taskno column (or not
explicitly setting that column) the re-writer will substitute 
  
  nextval(('currentcall_cadc_taskno_seq'::text)::regclass)

And that will be evaluated once for the insert and again for the rule.

this is documented somewhere.... I think
