This thread made me try this example. Note that there's a WARNING in the spot
where I pressed tab.
alvherre=# create or replace function foo (out pg_class) language plpgsql as $$ declare i pg_class%rowtype; begin for i
inselect * from pg_class loop return next; end loop; end; $$;
ERROR: cannot use RETURN NEXT in a non-SETOF function en o cerca de «next»
LINEA 1: ...begin for i in select * from pg_class loop return next; end ...
^
alvherre=# set lc_messWARNING: problem in alloc set PL/PgSQL function context: detected write past chunk end in block

The reason I tried to change lc_messages is that the spanish message
struck me as a bit odd and wanted to see what the english message looked
like.
The full sequence required to create the message in a clean backend, regardless
of whether the foo(pg_class) function exists previously, is:
create function foo (out pg_class) language plpgsql as $$ declare i pg_class%type; begin for i in select * from
pg_classloop return next; end loop; end; $$;
create or replace function foo (out pg_class) language plpgsql as $$ declare i pg_class%type; begin for i in select *
frompg_class loop return next; end loop; end; $$;
create or replace function foo (out pg_class) language plpgsql as $$ declare i pg_class%rowtype; begin for i in select
*from pg_class loop return next; end loop ; end; $$;
set lc_mess <tab>
