Overview
WINDEV and WEBDEV 22 propose a 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.
Versions 20 and later
The Native Connector to PostgreSQL is now available in 64 bits.
New in version 20
The Native Connector to PostgreSQL is now available in 64 bits.
The Native Connector to PostgreSQL is now available in 64 bits.
Caution: This version of Native PostgreSQL Connector operates with WINDEV and WEBDEV version 22.
Note: The Native PostgreSQL Connector is an optional and free module that can be downloaded from the PC SOFT site.
Required configuration

Conditions for using Native PostgreSQL Connector

The Libpq.DLL DLL is requird by Native PostgreSQL Connector. This DLL is supplied with Native PostgreSQL Connector. It was re-compiled from the sources of PostgreSQL version 7.4.23 to be compatible will all the versions of Windows from Windows 98. It contains all the features required by the Native Connector and it is compatible with the most recent servers (8.3.6).
The Libpq.DLL DLL must be found:
  • On the development computer, in the setup directory of WINDEV and/or WEBDEV.
  • On the deployment computer, in the executable directory or in the Windows directory.
Note: The Libpq.dll file can be replaced by a more recent version. Make sure that you also copy/install all the dependencies of this DLL.
For example, to use the libpq.dll of PostgreSQL version 8.3.6, you must:
  • Copy the DLLs of the PostgreSQL client layer into the same directory. These DLLs are as follows: ssleay32.dll, libpq.dll, libeay32.dll, libintl3.dll, libiconv2.dll, krb5_32.dll, comerr32.dll, k5sprt32.dll, gssapi32.dll
  • Install the DLLs of Visual 2005 SP2 runtime (package that can be downloaded from Microsoft Web site).
The version of the postgreSQL client layer and the version of your server should be identical.
To do so, you must:
  • Copy the DLLs of the PostgreSQL client layer into the setup directory of WINDEV or WEBDEV on the development computer.
  • Copy the DLLs of the PostgreSQL client layer into the executable directory or into the Windows directory on the development computer.
  • Install the DLLs of Visual 2005 SP2 runtime (package that can be downloaded from Microsoft Web site).
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 the features required by the Native Access and it is compatible with the most recent servers (8.3.6).
Note: To use the SSL connections, you must install a PostgreSQL client layer version 9.1 or later.
