Ways to Change Default Parameters of Newly Registered Servers in pgAdmin 4

Introduction

pgAdmin 4 is a powerful graphical user interface (GUI) tool for managing PostgreSQL databases. It provides various features to manage databases, including creating and modifying server configurations. When you register a new server in pgAdmin 4, it uses default parameters for various settings. In this article, we will discuss the ways to change these default parameters for newly registered servers.

Accessing Server Settings

To access the server settings, follow these steps:

1. Launch pgAdmin 4 and connect to the server.
2. In the left-hand navigation pane, expand the server group and select the server.
3. Right-click on the server name and select Properties from the context menu.

Changing Connection Parameters

You can change various connection parameters, such as the port number, host name, or username, by modifying the Connection tab in the Properties dialog box. For example:

// Before "host": "localhost", "port": "5432", "database": "postgres", "user": "postgres", "password": "your_password" // After "host": "192.168.1.1", "port": "5433", "database": "mydatabase", "user": "myuser", "password": "mypassword"

Changing Server Properties

To change server properties, such as the maximum number of connections or the default encoding, you need to modify the Server tab in the Properties dialog box. For example:

// Before "Maximum Connections": 100, "Default Encoding": "UTF8" // After "Maximum Connections": 200, "Default Encoding": "UTF8_General_CI"

Changing Authentication Methods

To change authentication methods, such as enabling SSL or Kerberos authentication, you need to modify the Authentication tab in the Properties dialog box. For example:

// Before "SSL": false, "Kerberos": false // After "SSL": true, "Kerberos": true

Saving Changes

Once you have made the desired changes, click the OK button to save them. The changes will take effect the next time you connect to the server.
