PostgreSQL 8.3.5, 8.2.11等更新版本发布

色粉盒撒娇

　　这次发布的更新版本和上次更新版本发布的说明差不多，除了更改的版本号，还有就是对PostGIS的LTree做了说明——GiST索引。
　　原文如下：
　　The PostgreSQL Project today released minor versions updating all active branches of the PostgreSQL object-relational database system, including versions 8.3.5, 8.2.11, 8.1.15, 8.0.19 and 7.4.23. These updates are critical for users of GiST indexes and databases in some non-English languages and should be applied as soon as possible.

These releases, which fix issues that were reported less than two weeks ago, demonstrate the PostgreSQL Project's dedication to rapid deployment of all patches for any serious database issues.

GiST indexes are used for full text search, the LTree, Intarray and Earthdistance modules, and the very popular PostGIS geographic extension to PostgreSQL. In the last set of update releases we inadvertently introduced a bug which could cause some index entries to become lost. If you are running 8.3.4, 8.2.10 or 8.1.14 we recommend that you run REINDEX on all of your GiST indexes after upgrading.

There are 23 other minor fixes contained in these update releases, including time zone updates for Argentina, Brazil, Mauritius and Syria. See the release notes for full details.

As with other minor releases, users are not required to dump and reload their database in order to apply this update release; you may simply shut down PostgreSQL and update its binaries. Users skipping more than one update may need to check the release notes for extra, post-update steps. As previously announced, only versions 8.2.11 and 8.3.5 of the Windows binaries are being released, as we no longer support 8.0 and 8.1 on Windows.
