We understand that the following is acquirable in
pg_total_relation_size().
*Total Size of database
However, now, the following is unacquirable.
*Size of used space of the entire database
*Size of free space of the entire database
*Size of fragmentation area of the entire database
Is there any method of acquiring the above?
Thanks.
