I have to apologize. Its clear that I did not sufficiently test
accessibility with a non-owner postgresql account. Since I was able to
see the list of relations I guess I just assumed that I had access to
them. This message got me looking a little deeper and I found that the
documentation for GRANT and REVOKE seemed to imply that only the owner
would have any real access. Further testing seems to indicate that this
is the case and so the default is exactly what I wanted. ;) I knew I
should think a couple of more times before posting. Thanks everyone for
your responses.

You can restrict access on a table-by-table basis using the SQL
GRANT command. For instance, for web access using Apache server
side includes, the user nobody must have the appropriate access. I
allow web users to read a database but not change it, so for any table
a web user might need to read I run the command:
GRANT SELECT ON <<table name> TO nobody ;
Of course, for this to work the user 'nobody' must be already a
PostgreSQL user. BTW, the opposite of GRANT is REVOKE, which
you can use to revoke a database privilege for a PostgreSQL user.
