As of PostgreSQL 8.1 you can use the following:
http://www.postgresql.org/docs/8.1/static/functions-admin.html#FUNCTIONS-ADMIN-DBSIZE
Example query to obtain per-table on-disk size:
select tablename,
pg_size_pretty(pg_relation_size(tablename)) as size,
pg_size_pretty(pg_total_relation_size(tablename)) as total,
pg_relation_size(tablename)
from pg_tables
where schemaname = 'public' and tablename !~ '^pg_'
order by 4 desc;
