The body of a function is *always* treated by the planner as if it were a
dynamically created query. The fact we all use the "$$"s (or also the 's)
around the function body tells it all.
The PREPARE requires every session to do it upon connections, because prepared
statements are managed on a per-session basis.
What I don't understand is why the planner gets passed by during those
queries while it is at full steam during the "normal" queries.
But this could be due to my ignorance! :-)
