/usr/doc/postgresql-7.2.1/html/largeobjects.html

Section 2.2 says: The large object implementation breaks large objects up
into "chunks" and stores the chunks in tuples in the database. A B-tree
index guarantees fast searches for the correct chunk number when doing
random access reads and writes.

I would presume this to meant that a large object has no finite size
limitation apart from the database itself exceeding disk space limits.

(But I could be wrong, I'm not a PostgreSQL developer.)

BTW: This should probably have been asked on the pgsql-novice list.
