Prologue of psprintf() says

* Errors are not returned to the caller, but are reported via elog(ERROR)
* in the backend, or printf-to-stderr-and-exit() in frontend builds.
* One should therefore think twice about using this in libpq.

If an error occurs in psprintf(), it will throw an error which will
override the original error. I think we should avoid any stuff that
throws further errors.
