I'm relatively new to postgres myself, but I'll take a stab at this.
Anyone can feel free to correct me if I'm wrong.

You can insert the graphic file by declaring the type to be OID and using
lo_import().

For example:

create table graphics
(name text, graphic oid);

insert into graphics values ('pic1', lo_import ('gif1.gif'));

Check out the manpage for large_objects for more info.

BTW, does anyone know, once I create a large object, and it creates the
files xinv... and xinx..., how I can get rid of postgres's references to
these objects when I no longer need them.  (vacuum gives a notice that it
can't remove these even if I have physically removed the files from the
database's directory).
