Hope you don't mind me adding this to your answer. I thought there would be no point in opening another one. Thanks again!
- It's been a while, but the answer is "yes and no," I believe.
- No: The describe-schema command doesn't (last I heard) allow any modification.
- Yes: The describe-schema command *also* doesn't do anything that a `SELECT` statement from `information_schema` doesn't do, so something like this should work.
- ```sql
- SELECT
- column_name
- FROM
- information_schema.columns
- WHERE
- table_schema = 'public'
- AND
- table_name = 'auth_user'
- ORDER BY
- column_name ASC;
- ```
Assuming that they the PostgreSQL team hasn't moved anything in the years that I've had to deal with everything else, that should at least get you close.

- Another approach to get around the immutability of the [`psql`](https://www.postgresql.org/docs/current/app-psql.htm) meta-commands is to list the SQL queries that are executed by them, and modify the relevant parts (e.g., by adding an `ORDER BY` clause).
- For example, here's how to list the queries behind `\d`:
- ```
- $ psql -E -d my_db
- my_db=> \d auth_user
- ```
- or
- ```
- my_db=> \set ECHO_HIDDEN on
- my_db=> \d auth_user
- ```
- That will also show you the metadata query. Copy and paste that query and add your own `ORDER BY` clause.
