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

---------------------------------------------

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
