To enable remote access to Pgsql, the following steps need to be taken:

  1. Edit the configuration file of Pgsql: Open the configuration file of Pgsql, usually located in the /etc/postgresql//main directory. The file can be opened using any text editor.
  2. Locate and edit the listen_addresses parameter: Find the listen_addresses parameter in the configuration file and change its value to *, indicating it allows access from any IP address. If you only want to allow access from specific IP addresses, you can specify them accordingly.
  3. Edit the Pg_hba.conf file: The Pg_hba.conf file is used to configure the client authentication method for Pgsql.

    Access the Pg_hba.conf file, typically located in the /etc/postgresql//main directory.

  4. Edit the Pg_hba.conf file: In the Pg_hba.conf file, locate a line starting with “host” and modify it to the following format:
  5. Require all hosts to authenticate using the MD5 encryption method with the specified IP address or subnet mask.
  6. In this case, represents the allowed IP address or range of IP addresses for remote connections. “md5” indicates the authentication method using MD5 encryption. If other authentication methods are needed, they can be modified based on specific requirements.
  7. Save the configuration file and restart the Pgsql service: Save the modified configuration file and restart the Pgsql service to apply the changes.

After completing the above steps, Pgsql can now be connected to through remote access.
