Well, that's pretty interesting, but you haven't provided nearly enough
information for anyone else to reproduce the problem.  (No, a snippet of
C++ that depends on undescribed subroutines and uncertain context doesn't
do it.)

Perhaps you could turn on log_statement = all and capture the SQL that's
actually being sent to the server by this program?

Also, what version of Postgres is this exactly?
