![]() Alternatively, click the Data Source Properties icon ( ), or press Ctrl Alt Shift 0S. Right-click the data source and select Properties. Select the ones you need while setting up a connection to a new data source, or after the connection is established. To exit from the database, you can use the command \q. You can set the list of displayed databases and schemas in the Data Sources and Drivers dialog. Once you are connected, you can execute any normal queries. maybe connecting to database is the one you are missing. You are now logged into PostgreSQL testdb and ready to execute your commands inside testdb. Once if you are connected to postgres in your container, you can execute normal queries. Psql -h localhost -p 5432 -U postgress testdb ![]() You can select your database from the command prompt itself at the time when you login to your database. You are now connected to database "testdb" as user "postgres". Now, type the following command to connect/select a desired database here, we will connect to the testdb database.

You can check the available database list using \l, i.e., backslash el command as follows − In this article, you are going to see how simple it is to show all tables from PostgreSQL. You can select the database using either of the following methods −Īssume you have already launched your PostgreSQL client and you have landed at the following SQL prompt − 2 Ways to Show all Databases in PostgreSQL - KindaCode This concise and straightforward article walks you through a couple of different ways to view all databases (on your server) in PostgreSQL. Assume that we have already created a database in our previous chapter. Use the SELECT statement to query the user information from the pg_catalog.pg_user catalog.This chapter explains various methods of accessing the database. Another way to show tables in PostgreSQL is to use the SELECT statement to query data from the PostgreSQL catalog as follows: SELECT FROM pgcatalog.Use \du or \du+ psql command to list all users in the current database server.ORDER BY role_name desc Code language: SQL (Structured Query Language) ( sql ) Summary WHEN usecreatedb THEN CAST( 'create database' AS pg_catalog.text) WHEN usesuper THEN CAST( 'superuser' AS pg_catalog.text) The following statement returns all users in the current database server by querying data from the pg_catalog.pg_user catalog: SELECT usename AS role_name,ĬASE WHEN usesuper AND usecreatedb THEN CAST( 'superuser, create database' AS pg_catalog.text) The \du+ command adds an additional column called description. If you want to show more information, you can use the \du+ command: postgres=#\du+ Code language: Shell Session ( shell ) Second, use the \du to list all user accounts (or roles) in the current PostgreSQL database server: postgres=# \du Code language: Shell Session ( shell ) Once you enter the password for the postgres user, you will see the following PostgreSQL command prompt: postgres=# Code language: Shell Session ( shell ) It will prompt you for a password: Password: Code language: Shell Session ( shell ) Listing users using the psql toolįirst, connect to the PostgreSQL database server using the postgres user: $ psql -U postgres The output looks as follows: List of roles. Summary: in this tutorial, you will learn how to use the PostgreSQL list user command to show all users in a PostgreSQL database server. To see all predefined roles, you can connect to your RDS for PostgreSQL DB instance and use the psql du metacommand.
