There is "something better than row level locking" called MVCC, or
Multi Version Concurrency Control for short.

See Chapter 9 of the User Guide:

http://www.postgresql.org/idocs/index.php?mvcc.html

Hope that helps,

    I'd like to point out (for the new users around) that PostgreSQL
has had Multi Version Concurrency Control for quite some time. You don't
have to do anything special to use it. It's the default to handle
concurrency.
