Commands submitted in a single string are typically parsed and planned
before they are executed (though the behavior probably depends on
context and which PG version you're talking about). My advice is
don't do that.
If we were to do anything about it, it'd probably be to ban
multi-statement EXECUTE on security grounds ...
