-        Unlike <xref linkend="guc-shared-preload-libraries">, there is no
-        performance advantage to loading a library at session
-        start rather than when it is first used.  Rather, the intent of
-        this feature is to allow debugging or performance-measurement
-        libraries to be loaded into specific sessions without an explicit
-        <command>LOAD</> command being given.  For example, debugging could
-        be enabled for all sessions under a given user name by setting
-        this parameter with <command>ALTER ROLE SET</>.
