[pgpool-general: 4916] select count(*) as dummy from update_tbl1() goes to slave event when update_tbl1() is update function

[Avi Weinberg]

Hi,

In my system we had a workaround because of some system problem  that we call a function as "select count(*) as dummy from update_tbl1()" instead of "select update_tbl1()" as a result pgpool directs this call to the slave even when update_tbl1() is updating the database.

Your input is most welcome!

create table tbl1 (b int)
insert into tbl1 (b) values (1)

CREATE OR REPLACE FUNCTION public.update_tbl1()
RETURNS void AS
$BODY$
BEGIN
  update tbl1 set b = b+1;
END
$BODY$
LANGUAGE plpgsql VOLATILE


select count(*) as dummy from update_tbl1()
