There is no such privilege, and we're quite unlikely to invent one,
because it would be outside the SQL standard's privilege model.

You could probably enforce a requirement like this with a custom
event trigger.  But I'd encourage you to rethink why you think this
is a good idea.

You can setup a second database db2 just for u2 and have them access your
database db1 via foreign tables.  u2 still only has the SELECT privilege in db1
but can create objects in db2 and mess it up as they see fit.

If you go with a single database and event triggers as Tom wrote you must also
consider function security[0].  Otherwise u2 can override relations in s1 just
by creating compatible views in s2 and set search_path=s2,s1.  u2 can thus
inject data into functions that have no explicit search_path.
