I've created a C-Function a while ago that extracts the TOAST size for a 
given relation. This gave me the opportunity to do a pg_relation_size(oid) 
+ pg_relation_toast_size(oid) for a given table oid to calculate on disk 
data size required by a table. Maybe we should include such a function in 
core?
