The basic requirements for using the pgExpress Driver are:
libpqlibrary compatible with the server version the driver will connect.
Please install the 32 bits PostgreSQL distribution in your operating system, and the
libpq should be installed
along it. Most users will want to install PostgreSQL for
libpq and all its dependencies will be installed along it.
Another option is installing just the
libpq.dll and all its dependencies from the binary
package provided by the
libpqlibrary. It was meant to be easier to use/test the driver, however it was from an older version which is now deprecated in favor of newer version that have more dependencies.
libpqlibrary file (ex:
Linux)) and all its dependencies (ex:
MSVCR90.DLLetc.); otherwise, you'll likely run into runtime dependency errors.
