medical image on postgreSQL?

Dear Friends,

Apologize.. this posting may not relevance enough to this group.
I am very much a newbie to posgreSQL database programming and would like
assistance. I am finding an example how to use the database (postgreSQL)
to store MRI/CT image data using C language interface. I heard something
pronounced like: Content-Based Image Retrieval.. but I still do not have
any idea for a HowTo do on postgreSQL database.

If possible, could someone describe the skeleton for such database pro-
gramming.. nor if there are examples or some references/tutorial/books
concering this kind database programming, could someone give me pointers
to both the site online or book store.

Sorry if this is the incorrect place for this post, but I do need helps
and figured to start with. Thank you for your helps.
