Issue: pgAdmin Can’t Create Server

When trying to create a server in pgAdmin, you may encounter errors or issues that prevent the creation process. In this case, there are a few possible reasons and solutions to consider.

1. PostgreSQL Service Not Running

If the PostgreSQL service is not running on your system, pgAdmin won’t be able to create a server. To resolve this issue:

  1. Ensure that the PostgreSQL service is installed on your machine.
  2. Start the service by opening the command prompt or terminal and executing the appropriate command for your operating system:
    • For Windows: net start postgresql
    • For macOS/Linux: sudo service postgresql start

2. Incorrect Server Details

Double-check the server details you have entered in pgAdmin. Ensure that the following information is correct:

  • General: Verify that the name and the host address/IP are accurate.
  • Connection: Ensure that the port matches the PostgreSQL installation configuration (default: 5432). Also, check that the username and password are correct.

3. Firewall Restrictions

If you have a firewall enabled on your system, it may block incoming connections to PostgreSQL. Here’s what you can do:

  • Check if the firewall is running on your system and adjust the settings to allow incoming connections on the PostgreSQL port (default: 5432).
  • If the PostgreSQL server is running on a different machine, configure the firewall settings on that machine accordingly.

Example:

Let’s assume you are creating a server with the following details:

  • Name: MyServer
  • Host/Address: localhost
  • Port: 5432
  • Username: myuser
  • Password: mypassword

Make sure that PostgreSQL service is running, the details provided are correct, and any necessary firewall settings are adjusted to allow incoming connections. By following these steps, you should be able to create a server without any issues in pgAdmin.
