At the moment I can connect with PostgreSQL:

via ssh
via server ip. ip.ip.ip:5432/...
via all domain which added to nginx like domain1.com:5432 etc.
I want disabled connection via server ip and all domain which added to nginx

-h hostname
Specifies the IP host name or address on which postgres is to listen for TCP/IP
connections from client applications. The value can also be a comma-separated list of
addresses, or * to specify listening on all available interfaces. An empty value
specifies not listening on any IP addresses, in which case only Unix-domain sockets can
be used to connect to the server. Defaults to listening only on localhost. Specifying
this option is equivalent to setting the listen_addresses configuration parameter.

-i
Allows remote clients to connect via TCP/IP (Internet domain) connections. Without this
option, only local connections are accepted. This option is equivalent to setting
listen_addresses to * in postgresql.conf or via -h.

This option is deprecated since it does not allow access to the full functionality of
listen_addresses. It's usually better to set listen_addresses directly.
