One hard limit you'll run into is OIDs, which max at either 2^31 or 2^32
(I can't remember offhand which it is). That would be number of schemas,
and number of total tables (there's a unique index on pg_class.oid).
Actually, you'll be limited to 2 or 4 billion tables, indexes, and
views.
In reality, I suspect you'll become very unhappy with performance well
before those numbers. Running a database with just 10000 tables can be a
bit tricky, though it's certainly doable.
