BTW, what type do you have lo_1 declared as?  It strikes me that if it's
signed int32, and your OID counter is past 2 billion, this code would
fail because it would misinterpret a valid OID as negative.  The printf
would then report whatever the last error on the connection had been.
This still wouldn't explain why you're getting the duplicate-key error,
but it might at least point to the proper place to look.
