Beyond the Default: See All Available Databases in Your PostgreSQL Server with DBeaver

• PostgreSQL is a powerful open-source database management system. It can hold multiple databases within a single server instance.
• DBeaver is a popular graphical tool for managing databases, including PostgreSQL. It allows you to connect to your PostgreSQL server and view/manipulate the data.

By default, DBeaver might only show the first database it encounters on the server, which often happens to be the default one named "postgres". This doesn't prevent other databases from existing.

Here's how to see all databases in DBeaver:

1. Right-click on your existing PostgreSQL connection in DBeaver.
2. Select "Edit Connection".
3. Go to "Connection settings".
4. Look for the "Show all databases" checkbox (might be under the "Main" or "PostgreSQL" tab depending on your DBeaver version).
5. Check the box and save the changes.

1. Configuration Setting: This behavior is controlled by a setting within DBeaver, not by code running on the database server (PostgreSQL) or within DBeaver itself.
2. Database Discovery: DBeaver uses its drivers to communicate with the PostgreSQL server and discover available databases. The "Show all databases" option controls how DBeaver retrieves this information.

However, if you're interested in seeing code related to PostgreSQL itself, you could explore:

• DBeaver driver code: DBeaver uses drivers to connect to different database systems like PostgreSQL. These drivers might have some code related to how they discover and list available databases, but it wouldn't be directly related to the "Show all databases" setting.

1. psql command-line interface: PostgreSQL provides a powerful command-line tool called psql. You can use it to connect to your server and list all databases. Here's the command:

psql -l

This will list all databases along with their owner and access privileges for your current user.

1. SQL query: You can connect to your PostgreSQL server using any database client that supports SQL queries (including DBeaver in SQL mode). Then, execute the following query:

SELECT datname FROM pg_database;

This query retrieves the database name ("datname") from the system catalog table "pg_database". It will list all databases accessible to your connected user.

1. Other database client tools: Several other database administration tools can connect to PostgreSQL and display all databases. Some popular options include pgAdmin, phpPgAdmin, and Navicat. These tools usually have a dedicated section or view for browsing available databases.
