After I create the same name index on the heap table and the temporary

create table t1(c1 int);
create temp table t2(c1 int);

create index idx1 on t1(c1);
\di+
List of relations

Is it the expected bavior?

Yes, since the pg_temp schema has higher priority and those command will not
show multiple objects for the same non qualified name. You can either change
the priority with something like

SET search_path TO public, pg_temp;

to look at public (or any other schema) first, or explicitly ask for the schema
you want, e.g. \di+ public.*
