      Description

      This rule applies whenever an IF statement is followed by one or
      more ELSEIF statements; the final ELSEIF should be followed by an ELSE statement.

      The requirement for a final ELSE statement is defensive programming.
      The ELSE statement should either take appropriate action or contain
      a suitable comment as to why no action is taken. This is consistent with the
      requirement to have a final ELSE clause in a CASE
      statement.

      Noncompliant Code Example

      IF my_variable = 0 THEN
        do_something;
      ELSIF my_variable = 1 THEN
        do_something_else;
      END IF;
      

      Compliant Solution

      IF my_variable = 0 THEN
        do_something;
      ELSIF my_variable = 1 THEN
        do_something_else;
      ELSE
        -- Nothing has to be done.
        NULL;
      END IF;
