Community, is that behavior is explainable?
create or replace function dbo.func(result out int) as $$begin result = 1; end; $$ language plpgsql;
-- 1 --
do $$
declare
v_result int;
begin
select p.result from dbo.func(d) p into v_result;
exception when SQLSTATE '42601' then
raise '42601';
when others then
raise 'others';
end;
$$
--Exception is handled. This is OK.
ERROR: others
CONTEXT: PL/pgSQL function inline_code_block line 9 at RAISE
********** Error **********
ERROR: others
SQL state: P0001

do $$
begin
select p.result from dbo.func() p into v_result;
exception when SQLSTATE '42601' then
raise '42601';
when others then
raise 'others';
end;
$$
--Exception is not handled. This is the question.
ERROR: "v_result" is not a known variable
LINE 3: select p.result from dbo.func() p into v_result;
********** Error **********
ERROR: "v_result" is not a known variable
SQL state: 42601

I suppose the reason of such behavior in different steps of code parsing, but can`t find any discussions or topics in documentation.
Сould someone clarify the situation for sure?
