ERROR: functions with parameter defaults f007(integer, integer,
integer) and f007(integer, integer) are ambiguous
I think this should not return error as the input args here is
timestamp... inputs?
In theory yes, but it's currently not that smart. When it considers a
function based on available default values, it does not consider
argument types. So if there is another function with the same number of
arguments, it bails out.
Feel free to propose improvements.
