For example, how to sort the output below by the values in "Column" in the psql shell itself? my_db=> \d auth_user Table "public.auth_user" Column ...

Just adding a couple more tags (psql looks and sounds a lot like plsql ... better to add more tags to further differentiate)
How to sort the output of meta / slash commands in `psql`?
For example, how to sort the output below by the values in "Column" in the `psql` shell itself?
```
my_db=> \d auth_user
Table "public.auth_user"
Column | Type | Collation | Nullable | Default
--------------+--------------------------+-----------+----------+---------------------------------------
id | integer | | not null | nextval('auth_user_id_seq'::regclass)
is_superuser | boolean | | not null |
username | character varying(150) | | not null |
first_name | character varying(150) | | |
last_name | character varying(150) | | not null |
email | character varying(254) | | |
is_staff | boolean | | not null | false
is_active | boolean | | not null | false
password | character varying(128) | | |
last_login | timestamp with time zone | | |
date_joined | timestamp with time zone | | |
Indexes:
"auth_user_pkey" PRIMARY KEY, btree (id)
"auth_user_username_6821ab7c_like" btree (username varchar_pattern_ops)
"auth_user_username_key" UNIQUE CONSTRAINT, btree (username)
```
I know that this would be easy to do outside the `psql` shell, for example in Bash,
```
$ psql -U postgres -h localhost -d my_db -c '\d auth_user' | grep '^.*|' | sort -t'|' -k1
Column | Type | Collation | Nullable | Default
date_joined | timestamp with time zone | | |
email | character varying(254) | | |
first_name | character varying(150) | | |
id | integer | | not null | nextval('auth_user_id_seq'::regclass)
is_active | boolean | | not null | false
is_staff | boolean | | not null | false
is_superuser | boolean | | not null |
last_login | timestamp with time zone | | |
last_name | character varying(150) | | not null |
password | character varying(128) | | |
username | character varying(150) | | not null |
```
but I'm curious if this could be done in `psql` at all.
