Can you try to recreate the call flow as implemented here (it's
pretty much plain old C if you ignore error handling):
https://git.codesynthesis.com/cgit/odb/libodb-pgsql/tree/odb/pgsql/statement.cxx?h=bulk#n789
Except replacing `continue` on line 966 with `break` (that will
make the code read-biased which I find triggers the error more
readily, though I was able to trigger it both ways).
Then in an explicit transaction send 500 prepared insert statements
(see previous email for details) with 250'th having a duplicate
primary key.
