<para>
- If you are using <acronym>SSL</> inside your application (in addition
- to inside <application>libpq</application>), you can call
- <function>PQinitSSL(int)</> with <literal>0</> to tell
- <application>libpq</application> that the <acronym>SSL</> library
- has already been initialized by your application.
+ If your application initializes <literal>libssl</> or
+ <literal>libcrypto</> libraries and <application>libpq</application>
+ is built with <acronym>SSL</> support, you should call
+ <function>PQinitSSL(0)</> to tell <application>libpq</application>
+ that the <literal>libssl</> and <literal>libcrypto</> libraries
+ have been initialized by your application so
+ <application>libpq</application> will not initialize those libraries.
