The first release candidate for PostgreSQL 9.0 is now available. Please
download and test immediately so that we can move rapidly towards final
release. All known bugs should be fixed, so users should promptly report
any bugs which they find.
Note that, due to a system catalog change, an initdb and database reload
will be required for upgrading from 9.0 beta versions. We encourage
users to use this opportunity to test pg_upgrade. Please report your
results.
If you are able to help with testing, please see the testing page:
http://wiki.postgresql.org/wiki/HowToBetaTest
No changes in commands, interfaces or APIs are expected between this
release candidate and the final version. Applications which will deploy
on 9.0 can and should test against 9.0rc1. Depending on bug reports,
there may or may not be more release candidates before the final release.
