During a recent security review of our products, we identified that Tableau Server versions 2019.3.x - 2020.3.x embed a version of PostgreSQL Database (PGSQL 9.6) that will no longer be supported as of November 11, 2021. Any product versions released after this time (2020.4 and higher) will have the normal end-of-life end dates.
The versions noted here had an early end-of-life date to address any PostgreSQL security vulnerabilities discovered in these versions.
What is the impact?
The end-of-maintenance date for Tableau versions 2019.3.x, 2019.4.x, 2020.1.x, 2020.2.x, and 2020.3.x is November 11, 2021. You can continue to use one of these versions but note that although Tableau Technical Support is available when your subscription or maintenance period is current, Technical Support will only assist with upgrade issues to help you move to the correct supported version. In addition, these old versions will no longer be receiving updates to provide new security fixes or correct defects.
This change also applies to companion client software for these versions, including Tableau Desktop, Tableau Prep, Resource Monitoring Tool, Content Migration Tool, and others. You should upgrade to version 2020.4 or newer as quickly as possible.
