Hi, I have a partitioned table(partitioned on date) .There are about 1 million insertions per day. There is a column called mess_id. This column is updated .But update query is taking huge time.When i checked , this column is not unique, and most of the time its having null . Say everyday out of 1 million only 20K rows are not null for this column ;.Insertions are happening very fast , but update is very slow. How to optimize my update query? Is it good to create index on that column .. i m worried about my insertions getting slow Rgrds Suhas -- View this message in context: http://postgresql.1045698.n5.nabble.com/CREATING-INDEX-on-column-having-null-values-tp5735127.html Sent from the PostgreSQL - performance mailing list archive at Nabble.com. -- Sent via pgsql-performance mailing list (pgsql-performance@xxxxxxxxxxxxxx) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-performance
