        Set this role's session default for the specified configuration
        parameter to the given value.  If
        <replaceable>value</replaceable> is <literal>DEFAULT</literal>
        or, equivalently, <literal>RESET</literal> is used, the
        role-specific variable setting is removed, so the role will
        inherit the system-wide default setting in new sessions.  Use
        <literal>RESET ALL</literal> to clear all role-specific settings.
        <literal>SET FROM CURRENT</literal> saves the session's current value of
        the parameter as the role-specific value.
        If <literal>IN DATABASE</literal> is specified, the configuration
        parameter is set or removed for the given role and database only.
