[ADMIN] uuid extension not available

[Thara Vadakkeveedu]

Hi
I have postgresql 9.2 installed on red hat linux 6.4 . I need to generate uuids 
using the uuid_generate_v4() function.
 
select * from pg_available_extensions does not list this extension. The only 
extension that is available is plpgsql.
 
I find uuid libraries, libuuid.so.1 and libuuid.so.1.3.0 in /lib64 folder.
 
What should I do next ? How can I can install this extension ?
 
Thanks,
Thara.
