What is the data at your disposal when trying to select the current year? If it is a timestamp, simply use date_part:
=# select date_part('year', now());
 date_part

It is *datetime*. Now my users are created at different date...

say -

user1   24/02/1997
user2  28/02/2011
user3  02/03/2001
user4  01/03/2003
.....

But I have some requirment, where date/month part will be as it is... but as per the current year, I will replace the actual year with the current year, while I will be displaying it. To meet this need, I am currently doing as 

  select  to_char(created_at,'DD/MM') || '/' || to_char(now(),'YYYY') as when from users;
