Connect with psql

psql is a command line tool for PostgreSQL®, useful to manage and query your database.

Variables​

These are the placeholders you will need to replace in the code sample:

VariableDescription
POSTGRESQL_URIURL for PostgreSQL connection, from the service overview page

Prerequisites​

For this example you'll need psql already installed on your computer

Connect to PostgreSQL​

From your terminal, execute the following code:

psql POSTGRESQL_URI

The output should look like the following if the connection is successful:

psql (13.2, server 13.3)
SSL connection (protocol: TLSv1.3, cipher: TLS_AES_256_GCM_SHA384, bits: 256, compression: off)
Type "help" for help.

defaultdb=>

To confirm that the connection is working, issue the following code checking the PostgreSQL version:

select version();

The result will be similar to the following:

version
--------------------------------------------------------------------------------------------
PostgreSQL 13.3 on x86_64-pc-linux-gnu, compiled by gcc, a 68c5366192 p 6520304dc1, 64-bit
