That's pretty interesting.  I was not able to reproduce this failure
using stripped-down table definitions --- I tried

create table foo (f1 int);
create table bar (f1 int);
create table baz (f1 int);

insert into foo(f1)select distinct f1 from barwhere not exists (select foo.f1 from baz wherefoo.f1 = bar.f1);

So I think there must be some special feature of your tables that you
haven't shown us.  Could we see a schema dump (pg_dump -s) for these
tables?

BTW the inner select seems pretty weird --- what is the point of joining
against table_brut when you're not using it?  But that doesn't look like
it could provoke this error.
