Problem Description:
- --------------------
Whenever an attempt to create a large object is made, be it
via SQL or LIBPQ it errors and drops out with the error

pqReadData() -- backend closed the channel unexpectedly.
    This probably means the backend terminated abnormally before or while processing the request.
We have lost the connection to the backend, so further processing is impossible.  Terminating.
