Tableau Server on Windows Help

When there is a change in the PostgreSQL major version requirement for Tableau Server, there are some specific instructions you must follow to ensure that your Tableau Server upgrade is successful. For example, Tableau Server 2020.4 requires that the repository use PostgreSQL version 12. This is a major version change from PostgreSQL version 9.x used in Tableau Server versions earlier than 2020.4. So if you are upgrading from an earlier version of Tableau Server to version 2020.4 or later, you will need to take the steps described in the following sections to complete the upgrade.

This topic also includes the product compatibility between PostgreSQL and Tableau Server.

Before you upgrade

You cannot do an in-place upgrade to update the PostgreSQL version on your existing PostgreSQL DB instance on Amazon RDS or Azure Database for PostgreSQL DB. Instead, you must create a new instance and point the Tableau Server to the new instance during upgrade. Use the following information to create a new instance and prepare for the upgrade:

1. Create a new instance of PostgreSQL Database instance:
   1. Create a PostgreSQL DB Instance on AWS Relational Database Service (RDS)
   2. Create a Azure Database PostgreSQL Instance on Azure
   3. Create a PostgreSQL Instance on Google Cloud
   4. Create a PostgreSQL Database as a Stand-alone Installation
2. SSL connections are not required but recommended. If you want to setup SSL connections for communications between Tableau Server and the External Repository, do the following:
   • Amazon RDS: See Using SSL to Encrypt the Connection to a DB Instance(Link opens in a new window).
   • Azure Database: See Configure TLS connectivity for Azure Database for PostgreSQL(Link opens in a new window).
   • Google Cloud Instance: See Configuring SSL/TLS certificates
   • Stand-alone PostgreSQL Instance: See Configure SSL .

3. Create a configuration file for the new instance you created in step 1.

   Create a json file with the following configuration settings:

   {
    "flavor":"<flavor name>",
    "masterUsername":"<admin user name>",
    "masterPassword":"<password>", 
    "host":"<instance host name>",
    "port":5432
   }
   

   • flavor: This is the type of external service you are going to use for Tableau Server repository.

     • Amazon RDS: use “rds”
     • Azure Database: use "azure"
     • Google Cloud Database: use "gcp"
     • Stand-alone PostgreSQL database: use "generic"

   • masterUsername:

     • Amazon RDS: Use "rails" for the user name. This is the user that you specified when creating the RDS instance.

       You must use "rails" as the masterUsername. This is required for the external repository to work with Tableau Server properly.

     • Azure Database, Google Cloud Instance or Stand-alone PostgreSQL Instance: Choose a user name that meets your requirements. We recommend using postgres as the Administrator user name. If you choose to use a different user name, make sure that the user name does not start with pg, or azure. The user name also cannot be rails, tblwgadmin, tableau, readonly, or tbladminviews.

   • masterPassword: This is the same password you specified when creating the PostgreSQL database instance.

   • host: This is the endpoint of your PostgreSQL database instance.

   • port: The database port you specified when creating the PostgreSQL DB instance. Default port for PostgreSQL is 5432.

Tableau Server Upgrade

Note: If you are using Tableau Server External Repository, you must upgrade Tableau server using the command line option.

The following are the high level steps of how to specify the external repository parameters when running the upgrade script.

For a full walk-through of Tableau Server upgrade process, see Upgrading from earlier versions.

1. On the Tableau Server, open a command prompt as administrator.

   Note: You must open a new command window because the Setup program updates the path for the new installation.

2. Navigate to the scripts folder for your new installation.

   By default:

   C:\Program Files\Tableau\Tableau Server\packages\scripts.<version_code>\

3. Run the upgrade script and specify the configuration file and the SSL certificate:

   upgrade-tsm.cmd --external-repository-config-file=<json config file> --external-repository-cert-file=<SSL certificate file>
