Summary: in this tutorial, you will learn how to show tables in PostgreSQL using psql tool and pg_catalog schema.

$ psql -E -l
********* QUERY **********
SELECT d.datname as "Name",
       pg_catalog.pg_get_userbyid(d.datdba) as "Owner",
       pg_catalog.pg_encoding_to_char(d.encoding) as "Encoding",
       d.datcollate as "Collate",
       d.datctype as "Ctype",
       pg_catalog.array_to_string(d.datacl, E'\n') AS "Access privileges"
FROM pg_catalog.pg_database d
ORDER BY 1;

                                  List of databases
   Name    |  Owner   | Encoding  |   Collate   |    Ctype    |   Access privileges

           |          |           |             |             | postgres=CTc/postgres

\dt<dt> command inside psql.  Then all you need to do is to figure out how to combine both queries into one.<br />

<div class="signature">Keep Calm and Carry On</div></dt>

psql -E test -c "\dt". You can then take that output and combine with the previous one to get a listing of all tables across all databases.<br />

<div class="signature">Keep Calm and Carry On</div>

SELECT * FROM pg_catalog.pg_tables WHERE schemaname != 'pg_catalog' AND schemaname != 'information_schema';

USE database my_database
