The PostgreSQL ODBC driver used by Tableau Server was upgraded to version 09.03.0300.
The version of PostgreSQL used by Tableau Server was upgraded to 9.3.4. This upgrade resolves a PostgreSQL issue that, for some customers, resulted in increased database size and decreased performance. This problem resulted in many repetitions of "WARNING: pgstat wait timeout" in the PostgreSQL log files. Customers that worked around this issue using” tabadmin set pgsql.use_vacuum_job=true” need to reset this value to the default using "tabadmin set pgsql.use_vacuum_job=false". Tableau recommends you do the reset before upgrading, but you can do so immediately after installing the new version if you need to.
Some errors (for example, an error generated by a missing data source) could restrict access to the Data Sources page for administrators. Non-administrative users could navigate to the page, but an administrator would get an "internal error" message.
Using ODBC drivers to connect to an Oracle Business Intelligence Enterprise Edition (OBIEE) data source published with "Prompt User for Credentials," would return the following error: "An unexpected error occurred on the server. If you continue to receive this error please contact your Tableau Server Administrator."
When restoring a backup after an upgrade, the tabadmin restore command could fail due to a backup error that was not noted in warning or error messages. This was due to the backup.sql file not being added to the .tsbak file during the Backup step, so it could not be restored to the server.
When a workbook view containing a map was published to Tableau Server, the map legend range indicator text would sometimes be cut off after a filter selection was made.
Refreshing an extract would generate a "could not determine a constructor for the tag !binary" error message. The problem would only occur when manually selecting a schedule and clicking "Run Now" and when the workbook name contained double-byte characters.
In a distributed environment (1 primary node, 2 worker nodes), the standby data engine and repository would be intermittently unavailable. The problem would occur during refreshes of large extracts (> 1 GB).
For the Guest User account, text for download links, share links, tooltips, and other UI text, would be displayed in the incorrect language. This problem was caused by User Preferences being incorrectly saved for the Guest User account.
