Ok, I think I am getting closer. The problem seems to be that the
"parameters" of the prepared query are never set. If I use
```
cur.execute("SELECT $1;", parameters=(42,))
```
instead of
```
cur.execute("SELECT 42;")
```
everything works as expected.
For the original, non-parameterized query, I was able to confirm that
`parameters_` is empty when reaching `PreparedStatement::select`
Not sure if this is a bug in ADBC because it does not set the parameters. I
guess ADBC skips the call to `DoPutPreparedStatementQuery` in this case. Not
sure if this is a client-side bug in ADBC. But even if it is, I guess the
server should be robust against this and report an error?
