PostgreSQL: ALTER TABLE to change Fillfactor Value

This is one of the important post related to change or set the Fillfactor value for the existing table of the PostgreSQL.

One of our table is very busy with heavy updates and accessing by multiple clients.
I have also estimated the row size of that table which is not that much bigger, so I have decided to change Fillfactor of that table.

I have recently published an article about the importance of Fillfactor in PostgreSQL.

Please Note:
After changing the value of Fillfactor, you should execute VACUUM FULL on that particular table.
After changing the value of Fillfactor, it works only for new tuples.
