Need to calculate total size of a table along with BLOB data assosciated with it.

[girish R G peetle <giri.anamika0@xxxxxxxxx>]

Hi,

PostgreSQL system function, pg_total_relation_size() doesn't include BLOB data size that is associated with the table. 

TAR dump restore fails if the BLOB data size associated with a table is more than 8GB. (Which is limitation of TAR format).

I know we can switch to compressed dump format. But wanted to know if there a way to know true size of a table. 

Thanks
