sql - where not exists error in upsert function -

-

i have gotten lot of writing strong upsert function postgresql. trying insert values table 3 columns, 2 foreign keys, , 1 text.

i have similar function works great, not have subqueries 1 does. getting error 

"error:  syntax error @ or near "where" line 24:   not exists (select 1 sel)"

the function:

create or replace function upsert_dish_cluster_to_network(n_id int, c_id int, amsover text) returns setof dish_cluster_to_network  $func$ begin  loop     begin      return query     sel (         select dctn.id           dish_cluster_to_network dctn          dctn.network_id = (select id unv_network amscode = n_id)         ,    dctn.cluster_id = (select id dish_cluster_network axsyscode = c_id)            share         ),          ins (         insert dish_cluster_to_network (network_id, cluster_id, amsname_override)         values (             (select id unv_network amscode = n_id),             (select id dish_cluster_network axsyscode = c_id),             amsover             )         not exists (select 1 sel)         returning *         ),          upd (         update dish_cluster_to_network dctn         set    network_id       = (select id unv_network amscode = n_id),                cluster_id       = (select id dish_cluster_network axsyscode = c_id),                amsname_override = amsover           sel          sel.id = dctn.id         ,    (      dctn.network_id    distinct (select id unv_network amscode = n_id)             or    dctn.cluster_id    distinct (select id dish_cluster_network axsyscode = c_id)             )         returning dctn.*         )     select * ins     union     select * upd;      return;      exception when unique_violation         raise notice 'something bad happened';     end; end loop;  end $func$ language plpgsql;

i cannot figure out why not have not exists line. if comment out line function inserts new entries , never updates.

there no where clause insert command. replace values select

ins (     insert dish_cluster_to_network (         network_id, cluster_id, amsname_override     )     select        (select id unv_network amscode = n_id),        (select id dish_cluster_network axsyscode = c_id),        amsover     not exists (select 1 sel)     returning * ),
