Email address: robert(dot)nilsson(dot)123(at)gmail(dot)com
PostgreSQL version: 16.0
Operating system: Ubuntu 11.4.0 (x86_64)
Description:

psql client version is psql (16.0 (Ubuntu 16.0-1.pgdg22.04+1) on x86_64.

Connect to a database with psql from a terminal.

Create a temporary table
CREATE TEMP TABLE test test ( id integer );

Make sure expanded format is off
database=> \x off

Display information about the table:
database=> \d test
Table "pg_temp_6.test"
Column | Type | Collation | Nullable | Default
--------+---------+-----------+----------+---------
id | integer | | |

Turn on expanded output
database=> \x on

Display the information about the table again:
database=> \d test
Table "pg_temp_6.test"
Column | Type | Collation | Nullable | Default
--------+---------+-----------+----------+---------
id | integer | | |

Expected to see output in expanded format, like this;
Table "pg_temp_6.test"
-[ RECORD 1 ]------
Column | id
Type | integer
Collation |
Nullable |
Default |

The related command \dt works as expected;
database=> \x off
database=> \dt test
List of relations
Schema | Name | Type | Owner
-----------+------+-------+-------
pg_temp_6 | test | table | user
(1 row)

database=> \x on
\dt test
List of relations
-[ RECORD 1 ]-----
Schema | pg_temp_6
Name | test
Type | table
Owner | user
