Re: volatile void returning function not executed as often as expected in sql function

When I send the mail, I saw it, the problem is that the function
should return setof void instead of void, then it works, sorry for
bothering.

pv=# --increase every a in foo by 1, but now in function
create or replace function foofunc2() returns setof void as
$func$
    select foofunc(a) from foo
$func$ language sql;


pv=# select foofunc2();
 foofunc2

(3 rows)

pv=# select * from foo;
  a
-----
   1
  11
 101
