The the schema that your tables are in wouldn't have any effect on the
"system" rights granted to roles on the server (such as the login
privilege or inheritance).

It's true that all users that can connect to a database have the CREATE
right in the public schema, but you can revoke that right from public
(and it's quite easy...(revoke create on schema public from public;),
and if you want this to be applied by default for all new databases,
just issue it in the template1 databases (this assumes that you always
use template1 as your template) . Also, keep in mind that once an
object is created in a schema, the owner is the only one with rights to
that object...so while you could have rogue users creating objects
(tables, sequences, indexes, etc.), they wouldn't be able to access
tables (or data in those tables) unless rights had been granted to them.
As such, the fact that your tables (a database is a superset of a
schema, so your tables would be created in the public schema inside your
database) are in the public schema shouldn't be much of an issue unless
you granted the public role rights to them.
