[GENERAL] Upgrade to 9.3 - performance issue ?
Hello, We were planing to upgrade from 9.0 to to 9.3. While investigating on the performance side, we stumbled upon a link which says there may be performance degradation on 9.3: http://postgresql.1045698.n5.nabble.com/upgrade-from-9-2-x-to-9-3-causes-significant-performance-degradation-td5771288.html So we are planning to do this post the upgrade: echo never > /sys/kernel/mm/transparent_hugepage/enabled echo never > /sys/kernel/mm/transparent_hugepage/defrag Wanted to understand, If there are any other such tweaks that we need to take care of, before we go 9.3 Some details: OS: CentOS 6.2 Kernel: 2.6.32-431.20.3.el6.x86_64 Help here is appreciated.

[GENERAL] Upgrade to 9.3
Hello, We are planning to upgrade Postgres from 9.0 to 9.3. Was wondering if there are any serious changes that I have to look out for (syntax/datatypes changes) so that my code does not break.
