psql doesn't show tables duplicated in multiple schemas - Mailing list pgsql-bugs

Setup 

----------------------

CREATE SCHEMA x;
CREATE SCHEMA y;

CREATE TABLE x.a(f int4);
CREATE TABLE x.b(f int4);

CREATE TABLE y.b(f int4);

CREATE TABLE y.c(f int4);

-----------------------

Test

-----------------------

docker=# set search_path=x;
SET
docker=# \d
       List of relations
 Schema | Name | Type  | Owner
--------+------+-------+--------
 x      | a    | table | docker
 x      | b    | table | docker
(2 rows)

docker=# set search_path=y;
SET
docker=# \d
       List of relations
 Schema | Name | Type  | Owner
--------+------+-------+--------
 y      | b    | table | docker
 y      | c    | table | docker
(2 rows)

docker=# set search_path=x,y;
SET
docker=# \d
       List of relations
 Schema | Name | Type  | Owner
--------+------+-------+--------
 x      | a    | table | docker
 x      | b    | table | docker
 y      | c    | table | docker
(3 rows)

I would expect last table listing to include 'y.b' table. Although shadowed when referencing by 'b' it's still there.

Tested with psql & postgres 13.3
