Flashback? I think you might be confusing this:
http://oracle.com/
with this:
http://postgresql.org/

Check out TOAST and pgcrypto in the *MANUAL*.
http://lmgtfy.com/?q=postgresql+manual
(The above too grumpy? Google is a key skill as a DBA, and asking people
to do your basic research for you for free and hand the answers to you
on a platter is a bit much.)
> 3. DB Link and Heterogeneous Concept
"Hetrogenous Concept"?
dblink is, again, something best learned about using the documentation
and Google.
> 4. Storage Management
Details?
What do you want to know? "Storage management" is kind of a broad
category. You probably want to read the manual first, then look into
things like tablespaces, TOAST, vacuum and autovacuum, etc.
