Oh, wait. Though you didn't say it explicitly, I guess
you're implying that it is libpq the one that splits the
thing into the individual SQL statements and then send
each of those to the backend? (wrapped around a
transaction?)

Well, I was under the impression that the backend would
receive *one* command with *one* string that contains
all the SQL's separated by semicolons. This is what I
thought might be removed in future releases, if it is
considered that it's an unnecessary extension, etc.
