PostgreSQL 9.0 Beta 3 available now!

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.

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.
