kovrus opened a new pull request #7057: Use strict ISO8601 datetime format in postgres engine spec
URL: https://github.com/apache/incubator-superset/pull/7057
 
 
   The `PostgresEngineSpec` have the default implementation of the `convert_dttm` method that follows the `%Y-%m-%d %H:%M:%S` date time format. Despite the fact that the particular format is supported by PostgreSQL, it is not ISO8601 compliant, see section [4.3.2(http://dotat.at/tmp/ISO_8601-2004_E.pdf). The standard permits to omit the time designator `T`, but does not imply permission to replace it with space.
   
   Therefore, it would be harder to use Superset with databases that support the PostgreSQL Wire Protocol and strictly follow ISO8601. This PR improves Superset integration with such databases.
