I'd bet on PHP submitting the query via extended query protocol (PQexecParams or equivalent) instead of plain ol PQexec which is what psql uses. I don't speak PHP or have it installed here, so this example is hard for me to investigate. Can someone make a reproducer that uses PQexecParams? regards, tom lane
