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.
