Native PostgreSQL Connector for WINDEV and WEBDEV

Available only with this kind of connection

Overview

WINDEV and WEBDEV 26 offer an Native Connector to PostgreSQL (also called native access to PostgreSQL), available in 32 and 64 bits.. This Native Connector allows you to access a PostgreSQL database from a WLanguage program without using any external driver.

Caution: This version of Native PostgreSQL Connector operates with WINDEV and WEBDEV version 26.

Remark: The Native PostgreSQL Connector is an optional and free module that can be downloaded from the PC SOFT site.

Required configuration

Conditions for using a Native Progress Connector

We recommend that you use a recent PostgreSQL client layer, whose version is identical to the version of your server if possible.

To do so, you must:

Copy the DLLs of PostgreSQL client layer into the setup directory of WINDEV or WEBDEV on the development computer.
Copy the DLLs of PostgreSQL client layer into the executable directory or into the Windows directory on the development computer.
Install the DLLs of Visual runtime (package that can be downloaded from Microsoft site).
Remark: The version of visual runtime depends of PostgreSQL client layer.

In 32 bits, if these DLLs are not found, the Native PostgreSQL Connector will be using a standard client layer corresponding to the version 7.4.23 of PostgreSQL. It contains all features required by the Native Access and it is compatible with the most recent servers (8.3.6).

It is necessary to install the postgresql client layer with the package manager of the Linux distribution. The outbuildings will also be installed.
Example (debian):

apt-get install libpq5

Remark: To use the SSL connections, you must install a PostgreSQL client layer version 9.1 or later.
