HOT doesn't seems to be working in our case.
This is "table1" structure :
id integer not null
code integer not null
crid integer not null
status character varying(1) default 'A'::character varying
delta1 bigint default 0
delta2 bigint default 0
delta3 bigint default 0
delta4 bigint default 0
tz_id integer default 0
Indexes:
"idx1" PRIMARY KEY, btree (id)
"idx2" UNIQUE, btree (code, crid)
"idx3" btree (tz_id)
"idx4" btree (status)
code as crid are foreign key.
Here delta* fields get updated through out the day. and most of the time it may update the same row again n again.
table1 contains around 12843694 records.
Now not understanding y HOT don't work in our case.
Changed fillfactor to 80, 75,70.... but nothing seems to work.

No. HOT is always working, if it can. You don't need to configure it.
HOT is only available in 8.3 and 8.3.1
You DO need to upgrade to get the benefits of HOT
