Author：JIYIK Last Updated：2025/04/27 Views：

This article will discuss creating schemas in PostgreSQL using SQL queries or psql.

`CREATE SCHEMA`Use the statement to create a pattern in SQL query

To create a new schema, execute the following command.

CREATE SCHEMA test_schema

To view all schema names in the database, run the following query:

SELECT schema_name
FROM information_schema.schemata

You can also use this query to see all the schemas in the database:

SELECT *
FROM pg_catalog.pg_namespace
ORDER BY nspname;

`CREATE SCHEMA`Create a schema using the statement in PSQL

Using psql, you can perform more operations such as creating a database, connecting to the database, and finally creating the schema as follows:

CREATE DATABASE test_db;
\connect test_db;
CREATE SCHEMA test_schema;

To list all schemas in a database using psql, run the following command:

\dn

Output:

|    Name     | Owner |
--------------|--------
| public      | user1 |
| test_schema | user1 |
