[quote]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)
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.
