PostgreSQL国产化适配申威处理器编译问题

当前信创工作越来越引起人们的重视，其中，很多软件都有适配国产芯片的要求。对此，我们尝试在申威架构下编译按照PostgreSQL。并将其中遇到的问题以及解决办法记录下来。

编译问题

遇到了如下问题：不能识别申威架构

[postgres@SW-72-48 postgresql]$ ./configure --prefix=/home/postgres/he3pg-xc
checking build system type... config/config.guess: unable to guess system type

This script (version 2022-01-09), has failed to recognize the
operating system you are using. If your script is old, overwrite *all*
copies of config.guess and config.sub with the latest versions from:

  https://git.savannah.gnu.org/cgit/config.git/plain/config.guess
and
  https://git.savannah.gnu.org/cgit/config.git/plain/config.sub

If config/config.guess has already been updated, send the following data and any
information you think might be pertinent to config-patches@gnu.org to
provide the necessary information to handle your system.

config.guess timestamp = 2022-01-09

uname -m = sw_64
uname -r = 5.10.0-39.0.0.21.sw_64

configure: error: cannot guess build type; you must specify one

解决办法：
参考申威平台编译安装程序时报错

# 执行如下命令即可得到能够识别申威平台的 config.guess 脚本, 再替换安装程序中的同名文件即可正常编译安装.
yum install libtool
yum install libtool-ltdl
yum install libtool-devel
find /usr/share/libtool -name config.guess

找到config.guess以及config.sub两个文件后，拷贝到postgresql/config目录下，替换掉原来的文件。再次运行，即可。
