Yes, I create large object as it reccomends
create type lo

internallength=4, externallength=10,
input=int4in, output=int4out,
default='', passedbyvalue
);
and have all the problems I say here about.

By the way, PostgreSQL's man create_type recommends another way to create
the large object type:
create type bigobj (
input = lo_filein,
output = lo_fileout,
internallength = variable
);

Can anybody tell me how should I implement lo_filein and lo_fileout in this
case?

Thank you, Mikhail.
