Re: Support plpgsql multi-range in conditional control

Dear hackers, my good friend Hou Jiaxing and I have implemented a version of the code that supports multiple integer range conditions in the in condition control of the for loop statement in the plpgsql procedural language. A typical example is as follows:

postgres=# do $$

declare

    i int := 10;

begin

    for i in 1..10 by 3, reverse i+10..i+1 by 3 loop

       raise info '%', i;

    end loop;

end $$;

INFO: 1

INFO: 4

INFO: 7

INFO: 10

INFO: 20

INFO: 17

INFO: 14

INFO: 11

do

postgres=#

Hope to get your feedback, thank you!
