It says no such thing about lo_create(). Now AFAICS lo_creat() doesn't
pay any attention to its argument --- the fact that it even takes one is
historical. So -1 or any other input value would behave the same.
But lo_create(-1) would try to create a LO numbered 2^32-1 which would
work the first time and not thereafter.

Looking at the code, it appears that lo_create(0) will behave like
lo_creat(), that is create a LO with an unspecified OID.
Your report seems a bit confused. Want to test a little more and
