允許遠程連接：
修改 pg_hba.conf 文件，在 “host all all 127.0.0.1/32 md5”下面添加一行：
host all all 192.168.1.106/24 md5
修改 postgresql.conf 文件，在 #standard_conforming_strings = on 下添加一行：
standard_conforming_strings = off
有的版本還需要檢查 postgresql.conf 文件中監聽地址是否能監聽客戶端：
listen_addresses = '*' # what IP address(es) to listen on;
