Hmm, actually, this same client executes several queries for that same session. For the first queries, I can clearly see the binds in postgresql.log. Only this third query that is being executed, it produces error and not binds are logged.
Also, there may the case, where the third query gets its bind parameter from the second query (as I understood the developer).

Raul

The other constraint on reporting parameters during error is that they
have to be sent by the client in text not binary mode.  I venture that
your client is sending them in binary.

(The reason for this restriction is to avoid the overhead of converting
binary to text for every query, which we'd have to do in advance of
knowing whether the query will throw an error.)
