[Proposal] Add \dAt [AMPTRN [TBLPTRN]] to list tables by Table Access Method in psql

Hi all,

I'd like to propose adding a new `psql` meta-command:

    \dAt [AMPTRN [TBLPTRN]]

This would list all user tables that are using a specific Table Access
Method (TAM), optionally filtered by table name pattern.

Why?
- Table Access Methods are increasingly used.
- There's currently no native `\d`-style way to explore which tables are
using a given TAM.
- Users often need to check or debug TAM-based extensions and it'd be
useful to have a shortcut.

Example usage:

    \dAt sometam        -- list all tables using sometam TAM
    \dAt sometam auto%  -- filter to tables starting with 'auto'

Would love to hear if this sounds like a useful addition — if so, I’d be
happy to work on a patch. Also, please let me know if something similar has
been discussed before.

Thanks,
Srinath Reddy Sadipiralla
