难怪我后来又没有找到4.8.3.2版本的下载链接了，原来是有bug，还好我只是在测试环境使用，接下来线上环境是不能用这个版本了，目前只能用4.8.3.1。
以下是原文：
There is an issue with the functionality of a product you are following on Pivotal Network.
A moderate vulnerability has been found for Pivotal Greenplum.
Impacted software:
- Greenplum Database 4.3.8.2 for Red Hat Enterprise Linux 5,6 and 7 v4.3.8.2 (greenplum-db-4.3.8.2-build-1-RHEL5-x86_64.zip) downloaded on June 27,2016
Details:
GPDB 4.3.8.2 was removed from Pivotal Network because of regressions found after the release. GPDB 4.3.8.2 is still supported,but Pivotal is discouraging customers from using this version. The issue found in 4.3.8.2 is the potential for database panic during certain queries when utilizing compressed spill files. Although not critical for all users of GPDB we consider this issue serIoUs enough to remove this version from general circulation.
Recommended action: Customers are recommended to downgrade from 4.3.8.2 to 4.3.8.1 to fully avoid the issue and this can be done using a binary swap from 4.3.8.2. Shut down the database,change to the 4.3.8.1 binary and restart the database. GPDB 4.3.9.0 will be released in the near future and will resolve the issue found in 4.3.8.2. Until that time,4.3.8.1 is the recommended version of GPDB for customers prevIoUsly running 4.3.8.2 and customers are recommended to change to that version. If deciding to continue running GPDB 4.3.8.2,action can be taken to prevent the issues: Set the server configuration parameter using gpconfig 'gp_workfile_compress_algorithm' to the value 'none' to disable compression of workfiles. This will avoid the issues found in the release. 原文链接：https://www.f2er.com/postgresql/194452.html
