前言
Greenplum版本升级的详细过程，此博客做了详细的介绍。📣 1.升级简介
greenplum 升级分两种：
大版本升级：跨越主版本的升级，比如 4.3 or 5 升级到 6，6升级到7
小版本升级：主版本内的升级，比如6.x to 6.newer
✨ 1.1 大版本升级
Greenplum 从5.28版本开始可以直接使用gpupgrade工具升级到6.9及以后的版本
https://github.com/greenplum-db/gpupgrade
gpupgrade 是一个用于 Greenplum 数据库版本升级的工具，它提供了一种简单的方法来将 Greenplum 数据库集群从一个主要版本升级到另一个主要版本。
对于GP4.3版本的数据库，如果升级到6，需要通过备份恢复的方式，可以使用gpbackup、gprestore或gpcopy 工具来实现，这种方式同样适用于GP5 to GP6
以gpcopy命令，以4.3 升级到 6 为例，升级流程如下：
1）对原集群做好备份，并保证备份可用，如果升级失败需要原集群继续提供服务
2）准备GP6集群，保证集群状态可用
3）确保有足够的磁盘空间可以保留备份文件，建议数据库的5倍大小
4）如果磁盘不够，使用gpcopy（4.3.26及以上版本 or 5.9及以上版本）命令，不建议使用–truncate-source-after参数
5）对于GP6不兼容的扩展模块，需要在备份之前或者在restore的时候需要排除相关的表
6）GP6 的系统表、系统视图及函数变化比较大，留好操作日志，便于修复
gpupgrade 的升级流程大致如下：
1）确认环境：在开始升级之前，需要确认源和目标 Greenplum 数据库版本的兼容性，并确保升级环境满足一些先决条件，如空间和内存等资源。
2）预升级检查：运行 gpupgrade 工具的 pre-upgrade 子命令，它会检查是否满足升级所需的各种条件，例如必备软件版本、配置文件设置、备份等。
3）备份源数据库：在升级之前，需要对源数据库进行完整备份，以便在升级过程中发生意外情况时进行还原。
4）执行升级：运行 gpupgrade 工具的 upgrade 子命令，它会执行升级过程，包括关闭源数据库、备份源数据库、替换二进制文件、启动目标数据库等。
5）后升级检查：在升级完成后，运行 gpupgrade 工具的 post-upgrade 子命令，它会检查目标数据库是否成功启动，升级是否完成，并验证新版本的 Greenplum 数据库是否工作正常。
6）完成升级：在确认升级成功后，删除源数据库备份，清理 gpupgrade 工具的工作目录以及其他不必要的文件。
✨ 1.2 小版本升级
小版本升级步骤很简单，如下：
1、各个主机下载最新版本的安装包
2、master执行gpcheckcat -A检查所有库
3、master停库gpstop -a -M fast
4、直接安装新版本软件包：rpm -U open-source-greenplum-db-XXXXXX-rhel7-x86_64.rpm --nodeps
5、启库 gpstart -a
6、检查：gpstate -i
📣 2. 6.23升级到6.24
✨ 2.1 升级前检查
[gpadmin@master ~]$ gpcheckcat -A
Usage: gpcheckcat [<option>] [dbname]
-? | --help : help menu
-B parallel : number of worker threads
-g dir : generate SQL to rectify catalog corruption, put it in dir
-p port : DB port number
-P passwd : DB password
-U uname : DB User Name
-v : verbose
-A : all databases
-S option : shared table options (none, only)
-O : Online
-l : list all tests
-R test | 'test1, test2' : run this particular test(s) (quoted, comma seperated list for multiple tests)
-s test | 'test1, test2' : skip this particular test(s) (quoted, comma seperated list for multiple tests)
-C catname : run cross consistency, FK and ACL tests for this catalog table
Test subset options are mutually exclusive, use only one of '-R', '-s', or '-C'.
