FATAL: 28000: no pg_hba.conf entry for host "192.168.1.23", user "postgres", database "sde", SSL off
問題出現原因：pg數據庫和訪問數據庫的客戶端不在同一台機子上，然后保存
我遇到的情況，pg裝在了192.168.1.11上，訪問pg的程序在192.168.1.23上，建立數據庫連接的代碼報錯，內容如下：
FATAL: 28000: no pg_hba.conf entry for host "192.168.1.23", user "postgres", database "sde", SSL off
解決辦法：
在pg的安裝目錄下，找到pg_hba.conf文件，記事本打開，並編輯，照着紅色部門修改就行了。
# TYPE DATABASE USER ADDRESS METHOD
# IPv4 local connections:
host all all 127.0.0.1/32 md5
host all all 192.168.1.23/32 md5
# IPv6 local connections:
host all all ::1/128 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
