概述
Oracle_fdw 是一種postgresql外部表外掛，可以讀取到Oracle上面的資料。是一種非常方便且常見的pg與Oracle的同步資料的方法
配置Oracle環境
Oracle_fdw 的編譯依賴系統中需要有pg_config和Oracle的環境，如果沒有，就很難安裝成功，需要安裝一個。
安裝Oracle客戶端
- 從官網下載 instantclient-basic-linux.x64-12.2.0.1.0.zip、 instantclient-sdk-linux.x64-12.2.0.1.0.zip、 instantclient-sqlplus-linux.x64-12.2.0.1.0.zip三個檔案包，並放到/opt/oracle/目錄下
mv instantclient-basic-linux.x64-12.2.0.1.0.zip instantclient-sdk-linux.x64-12.2.0.1.0.zip instantclient-sqlplus-linux.x64-12.2.0.1.0.zip /opt/oracle/
- 解壓三個檔案包
unzip instantclient-basic-linux.x64-12.2.0.1.0.zip
unzip instantclient-sdk-linux.x64-12.2.0.1.0.zip
unzip instantclient-sqlplus-linux.x64-12.2.0.1.0.zip
- 解壓後會生成instantclient_12_2 目錄，將其更名為instantclient
mv instantclient_12_2 instantclient
下載和編譯安裝

使用
安裝完成之後，看動態庫中oracle_fdw.so y有沒有成功生成
解決使用依賴
ldd 這個動態庫檔案，會顯示缺少哪一些依賴。要把這些依賴都解決才能使用
