Since i'm not able to finish those other things in time, i wrapped up my 
existing code for this issue and came up with the attached patch, which 
should implement the behavior Tom proposed. These are two new functions 
pg_table_size() and pg_indexes_size(). This patch also changes 
pg_total_relation_size() to be a shorthand for pg_table_size() + 
pg_indexes_size().

Barring any objections i'm adding this to the CF.
