無法通過127.0.0.1

Question

我試圖用127.0.0.1作爲IP地址連接到PostgreSQL的本地實例連接到PostgreSQL，但連接始終否認：

⟩ psql -h 127.0.0.1 -U postgres -p 5432 
psql: could not connect to server: Connection refused 
    Is the server running on host "127.0.0.1" and accepting 
    TCP/IP connections on port 5432? 

我pg_hba.conf看起來是這樣的：

# TYPE DATABASE  USER   ADDRESS     METHOD 
# "local" is for Unix domain socket connections only 
local all    all          password 
# IPv4 local connections: 
host all    all    127.0.0.1/32   md5 
# IPv6 local connections: 
host all    all    ::1/128     trust 

我postgresql.conf有如下條目：

listen_addresses = 'localhost, 127.0.0.1' 
port=5432 
unix_socket_directories = '/private/tmp' 

但是我可以通過unix插座進行連接。還有什麼可以阻止連接？

不知道發生了什麼，但我的筆記本電腦硬重啓解決了這個問題。
