Accessing the Tables Submenu in pgAdmin

• The Tables submenu in pgAdmin allows easy access to table operations.
• It is hidden by default but can be enabled by checking ‘Show system objects’ in database properties.
• Other methods like SQL Editor, dialog boxes, tools provide additional ways to manage tables.
• Enabling the Tables submenu makes frequent table administration more convenient.

With pgAdmin, the Tables submenu allows you to manage the tables in your PostgreSQL database. However, this submenu is hidden by default. Here is how to open it:

Introduction

pgAdmin is a popular open source administration and development platform for PostgreSQL. It provides a graphical interface to easily interact with PostgreSQL databases.

One useful feature in pgAdmin is the Tables submenu, which lists all the tables in a selected database and allows you to perform operations like creating, editing, and dropping tables. However, this submenu is not visible by default.

How to Open the Tables Submenu

There are two methods to open the Tables submenu in pgAdmin:

Method 1: Right-click on the database

1. In the Browser pane, expand the Servers section and navigate to the database you want to manage tables for.
2. Right-click on the database name.
3. In the context menu, click on ‘Properties’.
4. In the Properties window, select the ‘Tables’ tab.
5. Check the box next to ‘Show system objects’.
6. Click ‘OK’ to save the changes.

The Tables submenu will now be visible when you expand that database in the Browser pane.

Method 2: Edit database properties

1. Right-click on the database and select ‘Properties’.
2. Go to the ‘Tables’ tab.
3. Check ‘Show system objects’.
4. Click ‘OK’ to save changes.

The Tables submenu will be enabled after this.

Why the Tables Submenu is Hidden by Default

The Tables submenu is hidden by default for PostgreSQL system databases like ‘postgres’, ‘template0’, and ‘template1’. This prevents accidental changes to critical system tables in these databases.

For regular databases created by users, the submenu is hidden to declutter the interface. Most users don’t need to constantly see the table objects.

Conclusion

The Tables submenu in pgAdmin allows for easy management of database tables. Unchecking ‘Show system objects’ exposes this useful submenu. With it enabled, you can now conveniently perform table operations like create, alter, drop etc from the graphical interface.

Frequently Asked Questions (FAQs)

Question: Does this work for all database types in pgAdmin?

Answer: Yes, the steps outlined above will expose the Tables submenu for any PostgreSQL database type in pgAdmin like – postgres, template0, template1, user-created dbs, etc.

Question: Where can I find the Tables submenu option?

Answer: The option to enable/disable the Tables submenu is found in the ‘Properties’ window of each database. Go to the ‘Tables’ tab and check/uncheck ‘Show system objects’.

Question: Is there a way to always keep it enabled?

Answer: Unfortunately, there is no persistent setting in pgAdmin currently to always show the Tables submenu. It needs to be enabled at a database level every time you want to access it.

Question: What permissions do I need?

Answer: You need adequate permissions on that database to edit its properties and enable the Tables submenu. Read-only users may not be able to access the submenu.

Additional Ways to Manage Tables in pgAdmin

While the Tables submenu provides easy access to table management, pgAdmin offers some other methods as well:

The SQL Editor allows you to write and execute SQL commands to create, alter, delete etc tables:

• Write SQL queries like CREATE TABLE, ALTER TABLE, DROP TABLE etc.

• Enter details and pgAdmin generates the SQL in background.
• Other dialogs like Alter Table, Drop Table etc. also available.
• Provides interfaces for visually managing tables.

Tools

The Tools menu has options like Restore, Import/Export, Backup etc:
