Why?

Apologies if this sounds patronising but I just wanted to check - you know that indexes are updated automatically when write operations occur, right?

I have responded on previously mail.
In my production system, there are lot of read write operation performed every hour.
That still doesn't answer why you feel you need to run reindex every hour. Do you have some measurements that show the index is bloating, or not performing well?

>Yes. You are correct.
OK - I think the folks here are having a hard time figuring out why you are reindexing so frequently, especially during times when the database is already under load.
What benefit does reindexing give you? Have you tried not doing it? The same goes for vacuuming - have you tried just letting autovacuum do its job, or tweaking its parameters to meet your needs?
(Also, list etiquette here seems to be to reply after the previous post, rather than “top-post”)
