Hi All,

One of our database size is 50gb. Out of it one of the table has 149444622 records. Size of that table is 14GB and its indexes size is 16GB.

Total size of the table and its indexes are 30GB. I have perfomred the below steps on that table.

reindex table table_name;

vacuum full verbose analyze on table_name;

But still the size of the table and its indexes size are not reduced. Please guid me. How to proceed further.
