Well, that's the problem: you can't. The SQL PREPARE command doesn't
have any provision for dealing with unspecified parameters. I think
this is reasonable since if it could, it would still have no way to tell
you what it resolved the parameter types as. The shortcoming here is
really in libpq and not in the backend: the protocol-level Parse
operation *is* designed to handle this scenario, but libpq isn't letting
you get at it.
Great, thank you, Tom, that's exactly the answer I was looking for. And if I understand a previous post from you, this functionality should be added to libpq, but you haven't had time and aren't sure what the API should look like, anyway, is that correct?
Is this the task labeled "llow libpq to check parameterized data types" here?:
