Direct-connect compatibility between clients and ArcSDE geodatabases in PostgreSQL

Which client and ArcSDE geodatabase versions are compatible for direct connections depends on the releases being used. The following is a table that summarizes which clients and geodatabases are interoperable when using a direct connection to the database:

9.3.x geodatabase

10 geodatabase

9.3.x client

Supported

10 client

Compatibility between ArcGIS clients and geodatabases in PostgreSQL

Connecting from newer clients to older release geodatabases allows you to use the geodatabase without having to upgrade the geodatabase at the same time the clients are upgraded. It also allows you to have mixed client installations at your site. For example, if one department uses a custom application that has not been updated to work with 10, you can keep the geodatabase at the 9.3 release, keep this group of users on a 9.3 client release, and upgrade the clients for the rest of the agency. Be aware, though, that the 10 clients cannot use 10 functionality until the geodatabase has been upgraded to 10.

ArcGIS Desktop, ArcGIS Engine, and ArcGIS Server 10 include all the direct-connect drivers for you to connect to an ArcSDE 9.3 or 9.3.1 geodatabase in PostgreSQL.

NoteNote:

Connections from a previous version client to a version 10 geodatabase are not supported.
