Philippe,
To include an external library, you'll need to use PL/PerlU, which
means you'll be creating the fucntion as the database superuser,
although other users can then invoke the function. Bytea doesn't have
file semantics like seek(), but it can be the output of a function, so
you should be good to go. I don't know whether the more file-like lo
interface can be used this way, but it's seldom worth the trouble
anyhow.
Cheers,
D
