How do I list all databases and tables using psql?

Please note the following commands:

• \list or \l: list all databases
• \dt: list all tables in the current database using your search_path
• \dt *.: list all tables in the current database regardless your search_path

You will never see tables in other databases, these tables aren't visible. You have to connect to the correct database to see its tables (and other objects).

To switch databases:

\connect database_name or \c database_name

See the manual about psql.

This lists databases:

SELECT datname FROM pg_database
WHERE datistemplate = false;

This lists tables in the current database

SELECT table_schema,table_name
FROM information_schema.tables
ORDER BY table_schema,table_name;

In Postgresql these terminal commands list the databases available

el@defiant$ /bin/psql -h localhost --username=pgadmin --list

Or the command stated more simply:

psql -U pgadmin -l

Those commands print this on the terminal:

                                  List of databases
   Name    |  Owner   | Encoding |   Collate   |    Ctype    |   Access privileges
-----------+----------+----------+-------------+-------------+-----------------------
 kurz_prod | pgadmin  | UTF8     | en_US.UTF-8 | en_US.UTF-8 |
 pgadmin   | pgadmin  | UTF8     | en_US.UTF-8 | en_US.UTF-8 |
 postgres  | postgres | UTF8     | en_US.UTF-8 | en_US.UTF-8 |
 template0 | postgres | UTF8     | en_US.UTF-8 | en_US.UTF-8 | =c/postgres          +
           |          |          |             |             | postgres=CTc/postgres
 template1 | postgres | UTF8     | en_US.UTF-8 | en_US.UTF-8 | =c/postgres          +
           |          |          |             |             | postgres=CTc/postgres
(5 rows)

These are the available databases.

In PSQL these commands list the tables available

You have to specify a database before you can list the tables in that database.

el@defiant$ psql -U pgadmin -d kurz_prod

This brings you to a psql terminal:

kurz_prod=#

Use the command \d meaning show all tables, views, and sequences

kurz_prod=# \d

This prints:

           List of relations
Schema |  Name   |   Type   |  Owner
--------+---------+----------+---------
public | mytable | table    | pgadmin
public | testing | sequence | pgadmin
(2 rows)

Then, to exit the psql terminal, type \q and press enter. Or Ctrl-D does the same thing. These are the tables in that database.
