I should point out, though I think you might be aware of this already,
that the patch actually behaves in the same way as the existing
implementation here. It will only normalise prepared queries that are
prepared with PQprepare() or its underlying wire-protocol facility. If
you run the example in the pg_stat_statements docs, where pgbench is
passed "-M prepared", that will work just as well as before. Perhaps
it's something that the patch should be able to do. That said, it
seems pretty likely that client libraries won't be dynamically
generating SQL Prepare/Execute statements under the hood.
