Tableau installs a postgres odbc driver along with Tableau Desktop as noted here (Driver Download | Tableau Software ). Currently, version 9.06 of this driver is being installed which is around 2 years old. The latest release is 11.01.
We identified and the postgres odbc developers have corrected a couple issues that make this driver work better with Tableau when using ODBC -> PostgresSQL to create the data source in Tableau. Specifically, "Correct the rgbInfoValue returned by SQLGetInfo(SQL_TIMEDATE_FUNCTIONS, ..)." solves a big issue with datetime columns accessed over ODBC, and is included in version 11.01 (https://odbc.postgresql.org/docs/release.html).
Can Tableau update their installer to include the most recent version of this driver instead of the 2 year old version of this driver? And perhaps put in place a process to keep this and other bundled drivers up to date?
