Yeah...

No; directly manipulating the system catalogs in dump scripts is a
crummy idea, because (a) it only works if you're superuser, and (b)
it creates a nasty backwards-compatibility problem if we change the
catalogs involved.
A CLUSTER command issued just after table creation, while it's still
empty, would be cheap ... but we don't put the index in place until
we've loaded the data, do we? Darn.
