PostgreSQL does not support the SHOW TABLES statement directly like MySQL does but provides users with an alternative. In this article, we will explore them in detail.
Using Psql Shell:
One way to list all the tables in a database is to use the below command after logging into the database:
Syntax: \dt
Example:
In this example, we will query for the list of all tables in the sample database, ie, dvdrental.
First, log in to the sample database using the below command:
\c dvdrental
Now use the below command to list the tables of the same:
\dt
Output:
Using pg_catalog schema:
Another way to show tables in PostgreSQL is to use the SELECT statement to query data from the PostgreSQL catalog as follows:
Syntax:
SELECT *
FROM pg_catalog.pg_tables
WHERE schemaname != 'pg_catalog' AND
schemaname != 'information_schema';
Example:
In this example, we will query for the list of all tables in the sample database, ie, dvdrental.
First, log in to the sample database using the below command:
\c dvdrental
Now runt the below command to list the tables in the database:
SELECT * FROM pg_catalog.pg_tables WHERE schemaname != 'pg_catalog' AND schemaname != 'information_schema';
