PostgreSQL version: 16.1

Description:        

``` SQL
gpadmin@gpadmin-host:~$ psql
psql (16.1)
Type "help" for help.

gpadmin=# create table t1(c1 int);
CREATE TABLE
gpadmin=# create temp table t2(c1 int);
CREATE TABLE
gpadmin=#
gpadmin=# create index idx1 on t1(c1);
CREATE INDEX
gpadmin=# create index idx1 on t2(c1);
CREATE INDEX

gpadmin=# \d+ t1

 c1     | integer |           |          |         | plain   |             |
             |

gpadmin=# \di+
                                          List of relations
  Schema   | Name | Type  |  Owner  | Table | Persistence | Access method |

 pg_temp_3 | idx1 | index | gpadmin | t2    | temporary   | btree         |
8192 bytes |
(1 row)

```
Both table `t1` and temp table `t2` have index idx, but `\di` only shows the
index of table `t2`.
