Connect to the PostgreSQL Database

You can verify the new PostgreSQL installation by connecting to the database using the SQL shell or the pgAdmin tool:

Connect to the PostgreSQL Database Using the SQL Shell (psql)

1. Open the SQL Shell (psql) in the PostgreSQL folder in the Start menu.

2. Enter the information for your database as defined during the setup process. Pressing Enter applies the default value, as shown in the square brackets.

Enter the database information into the SQL shell

3. Verify the new database by using the command:

select version();
Check the database version to verify the installation

Note: For more details on PostgreSQL version commands, check out our article on how to check PostgreSQL version.

Connect to the PostgreSQL Database Using pgAdmin

1. Open the pgAdmin 4 tool from the PostgreSQL folder in the Start menu.

Note: pgAdmin requires you to set a master password at first launch.

2. Right-click the Servers icon on the left-hand side. Select Create > Server to set up a new database server.

Create a new database server in pgAdmin

3. In the General tab, enter the name for the new database. In this example, we are using PostgreSQL as the database name.

Set the name for the new database server

4. In the Connection tab, enter the hostname (default is localhost) and password selected during the setup process. Click Save to create the new database.

Set the hostname and password and save changes to create a new database server

5. Expand the server display by clicking on the Servers > PostgreSQL icons on the left-hand side. Select the default postgres database.

Expand the server display to see the new database.

6. In the Tools drop-down menu, click Query Tool to open the query editor.

Select the new database and open the query tool.

7. Verify the database in the query editor by entering the following command and clicking the Execute button:

select version();

If the database is working properly, the current version of the database will appear in the Data Output section.

Verify the new PostgreSQL database in the query editor.
