使用fpm 方便快速生成postgresql extension分发包
fpm 是一个不错，而且强大的rpm、deb，系统启动服务工具包，我们可以用来快速的生成专业的软件分发包
演示一个pg 扩展包分发包的生成（rpm 以及deb）
安装fpm
sudo gem install --no-ri --no-rdoc fpmclone pg 扩展项目
代码已经写好了，使用plgo 参考https://www.cnblogs.com/rongfengliang/p/10672695.html
git clone https://github.com/rongfengliang/fpm-pg-extension-package-generate-demo生成rpm 包
- 生成
fpm -s dir -t rpm -n myplgo-extension ./example--0.1.sql=/usr/pgsql-10/share/extension/ ./example.control=/usr/pgsql-10/share/extension/ ./example.so=/usr/pgsql-10/lib/- 查看内容

./usr/pgsql-10/lib/example.so
./usr/pgsql-10/share/extension/example--0.1.sql
./usr/pgsql-10/share/extension/example.control生成deb 包
- 生成

演示的比较简单，主要是使用fpm 也很简单，我们不需要关注太多的包代码细节，直接使用就可以了，主要是进行配置而已
对于需要添加系统服务的也很简单，参考如下：
% fpm -s pleaserun -t rpm -n example /usr/bin/example
% rpm -qlp example-1.0-1.x86_64.rpm
