The third beta release for PostgreSQL version 9.0 is now available. This 
beta contains numerous fixes and several changes since Beta2, foremost 
among them a final clean-up of Streaming Replication and Hot Standby. 
Please download, install, and test it so that we can move towards final 
release of 9.0.

Some significant changes have been introduced in beta3 which will require 
some applications to be re-tested with 9.0. These include:

* Fixes for streaming replication and hot standby:
 	* close walwriter filehandles faster
 	* fsync on master before sending WAL
 	* improved handling of archive cleanup
           (including archive_cleanup_command
            and pg_archivecleanup contrib module)
 	* better handling of WAL record corruption
 	* change of standby delay settings and timing
* Fix for array handling in plpython
* Many dblink fixes
* TCP keepalive support in libpq
* Fix for checkSeek() behavior on old platforms
   (was causing pg_dump to occasionally fail)

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 Beta2 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: http://wiki.postgresql.org/wiki/HowToBetaTest

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.
