postgresql - 在 ec2 中升级 postgresql

Question

我在 ec2 实例中使用 postgresql 9.3.5(在一个单独的 ebs 卷中，如 http://aws.amazon.com/articles/1663 中所述)

我计划升级一个实例并将 ebs 卷附加到这个新实例。

新实例有postgresql 9.3.6
版本差异是否会导致使用数据库出现问题？

Answer 1

引用 PostgreSQL versioning policy :

Minor releases are numbered by increasing the third part of the version number, e.g. 9.2.3 to 9.2.4. The PostgreSQL team only adds bug fixes to minor releases. All users should upgrade to the most recent minor release as soon as possible. While upgrades always have some risk, PostgreSQL minor releases fix only frequently-encountered, security, and data corruption bugs to reduce the risk of upgrading. The community considers not upgrading to be riskier than upgrading

所以你是安全的。
