Sounds perfectly reasonable. You could either do it as a series of:
CREATE TABLE archive2007.foo AS SELECT * FROM public.foo;
or do a pg_dump of schema "public", tweak the file to change the
schema names and restore it.
the create table method won't copy the constraints + fkeys .
Shouldn't matter for an archive though, since you'd not want anyone to
have permissions. Still, pg_dump is my preference. Apart from anything
else, you can keep a copy of the dump around too.
