Dear friends,
I would like to know the particular table's insert,update and delete
record history.
I have done some googling and got to know about pg_stat_all_tables and
pg_stat_user_tables. These tables having this below field , which has the
tables insert,update and delete history,
n_tup_ins | bigint |
n_tup_upd | bigint |
n_tup_del | bigint |
But some time It was getting reset.. I don't know which scenario It is
happening.
Done the blow testing:
=> inserting,updating and deleting some record in a particular table
=> checked this pg_stat_all_tables entry, It has displayed perfect
count of the history.
=> restarted the server for check the these
(n_tup_ins,n_tup_upd,n_tup_del) entries.
but values weren't reseted, history remains.
=> Two days after I have checked this pg_stat_all_tables entry again,
but proper records wasn't there. Value of n_tup_ins,n_tup_upd and n_tup_del
was 0. I don't know why it has happened.
Please let me know the reason and which scenario it will get reset.
Whether I have to do any configuration related changes ?
Note:
I am using PostgreSQL 8.3.7.
