Hi
You can store binary files either as type oid or as type bytea.
See the Book of Bruce Momjian which is available online. There is a
chapter about Large Objects and how to store or retrieve. Or take a
look at the Documentation. I the Programmer's Guide there is
- Chapter 2: Large Objects
- Chapter 8.6 Storing Binary Data
In the User's Guide you may look at chapter 3.4 Binary Strings.

Conni
