I'm wondering if it was really more like
Parse/Parse/Bind/Bind/Execute/Execute/Sync, in which case the described
behavior wouldn't be too surprising at all.
I do note that if a transaction is implicitly started to execute these
messages, it's not closed until Sync. But that should only affect the
visibility of the results to other sessions, not to the current one.
There's definitely a CommandCounterIncrement in exec_execute_message ...
