I did; but I couldn't find what I need:

5.7.3.1 Methods

* public int getOID() - doesn't help

* public void close() - doesn't help

* public byte[] read(int len) / public int read(byte[] buf, int off, int len)
- doesn't help since I need writing, not reading

* public void write (byte[] buf) - doesn't help since I cannot specify the
offset

* public void write(byte[] buf, int off, int len) - doesn't help since the
offset mentioned is within the array, not within the LargeObject.

What I expected was a function like "seek()", but I couldn't find it there.
So, how can I append to an existing stream? Is there a function I have just
overseen? (PostgreSQL 7.3.2 Programmer's Guide)
