Prerequisites

PostgreSQL connector requires NPGSQL ADO.NET provider 4.0.10 to be installed. To install NPGSQL ADO.NET provider, go to release page and download the relevant release. The provider architecture (32-bit or 64-bit) needs to match the architecture of the product where you intent to use the connector. When installing, make sure that you select NpgSQL GAC Installation to ensure NpgSQL itself is added to your machine. The minimun supported PostgreSQL database version is version 9.4.

Known issues and limitations

The followings are some of the known limitations of using PostgreSQL connector:

  1. Insert row operation requires to provide explicit value for Primary Key column, even though default/autoincrement value is defined.
  2. Usage of the Order By parameter is recommended for Get rows action in order to get deterministic results in the output. If Order By isn't specified, the rows will be returned in an unspecified order. The actual order in that case will depend on the scan and join plan types and the order on disk, but it must not be relied on.
