For example MS Access. Unfortunately we can't expect to add
  OPENSSL_Applink() code snippet to such generic applications.

Psqlodbc uses libpq to establish SSL connections and gets the result
communication path using PQsocket() and/or PQgetssl(). Then
the driver communcates with the server via the commnication path
and doesn't call libpq APIs until the end of the connection.
The driver calls PQfinish() to terminate the connection.

It would be a problem if libpq and psqlodbc link different openssl
libraries.
