Does it necessarily have to be stored in a bytea field? Why not 
create your own type (CREATE TYPE) with utility functions to read 
the image file from disk?

PostgreSQL really needs a maintained type library as a single 
project where people can contribute types, functions, operators, and 
aggregates, such as the recently discussed email type.
