Hi,
I have an index on the user_id field in the query below:
myuser=# delete from clients where user_id like '64.22.91.%';
DELETE 22
Time: 220324.975 ms
Is there any reason why it's taking 220 seconds to run this simple
query? There are about 3 million rows in this table.
How can I debug this? How can I check if the index is bloated or
blown? From the VACUUM ANALYZE output, nothing like this is apparent.
Thanks.
