I want to create environment that allows the limited number of machines connect to my database server.
For debugging needs all IP address have the remote access to PostgreSQL server
listen_addresses = '*'
host all all 0.0.0.0/0 md5
I want to limit access. What is the canonical way to do that?
I though of using proxy server to connect from local machines to PostgreSQL server, but I'll appreciate other ideas.

Just change pg_hba.conf from
to rules you need. Columns are : type (leave host), database, username, IP, access method. For example, if you need to allow only 1.2.3.4 and 5.6.7.8 to connect any database using any username:
Use service postgresql reload (or smt like that, depending on your system) to apply changes.
