I want to configure PostgreSQL to accept connections only from a specified IP. It should not accept requests from any other IP.

回答1:

The following pg_hba.conf allows local and specified Ip have privilege login， but reject others。

# TYPE  DATABASE        USER            ADDRESS                 METHOD
local   all             all                                     trust
host    testdb          testuser      192.168.1.1/32             md5
host    all             all           0.0.0.0/0                 reject

The most easiest way is to make PostgreSQL listening only on localhost for incoming connections. The relevant parameter is listen_addresses in postgresql.conf. The docu is here.

Check the pg_hba.conf file in the data folder of PostgreSQL. This is the client authentication configuration file.

# TYPE  DATABASE        USER            ADDRESS                 METHOD
host    testdb           testuser      192.168.1.1               md5
local   testdb           all                                     md5

Add the above to the pg_hba.conf file
