The attached dbsize patch:
+ makes relation_size(relname) include toast tables;
+ adds aggregate_relation_size(relname) to count table data and indices;
+ adds indices_size(relname) to report the size of indices for a relation;
I've minimally tested it against PostgreSQL 8.1devel on i686-pc-linux-gnu,
compiled by GCC gcc (GCC) 3.2.2 20030222 (Red Hat Linux 3.2.2-5).
