The second beta release for PostgreSQL version 9.0 is now available. This beta contains numerous fixes and several changes since Beta1. Please download, install, and test it so that we can move towards final release of 9.0.
Some significant changes have been introduced in beta2 which will require some applications to be re-tested with 9.0. These include:
Note that, due to a system catalog change, an initdb and database reload will be required for upgrading from 9.0Beta1. We encourage users to use this opportunity to test pg_upgrade for the upgrade from Beta1 or an earlier version of 9.0. Please report your results.
If you are able to help with beta testing, please see the Beta testing page.
Betas are not stable and should never be used in production; they are for testing only. Additional beta releases, or a release candidate, will be available for testing in a few weeks.
Source code, as well as binary installers for many platforms, is available from the PostgreSQL Web Site:
