What is the purpose of the change
Add built-in generate_series function
Brief change log
Syntax:
generate_series ( start numeric, stop numeric [, step numeric ] ) → setof numeric
and it does n't support timestamp now, just like mysql
Returns:
When step is positive, zero rows are returned if start is greater than stop. Conversely, when step is negative, zero rows are returned if start is less than stop. Zero rows are also returned if any input is NULL. It is an error for step to be zero.
