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.
