PostgreSQL 发布了所有分支版本的更新，包括：9.2.2, 9.1.7, 9.0.11, 8.4.15, 和 8.3.22. 如果你正在使用 PG 的热备复制应该尽快在下次维护时升级。
该版本修复了一个显著的跟热备相关的页排序问题，该问题会导致在某些情况下索引损坏；该版本同时修复了某些情况下因为检查点和事务ID的时间问题导致数据损坏的问题；今天发布的更新同时修复了多个跟 CREATE INDEX CONCURRENTLY and DROP INDEX CONCURRENTLY 相关的问题，这些问题导致命令失败或者损坏索引，如果你使用了该特性应该使用 REINDEX 来重建受影响的索引。
此外这次更新还修复了 9.2 版本的一些 bug，主要包括：
Prevent psql crash due to incorrectly encoded input data
Fix pg_regress gmake build issues
Make sure correct directory is created for extensions
Fix some issues with buffer locks and VACUUM
