Which command can be used to display all roles and their attributes in PostgreSQL using psql?
Correct Answer:
A
Explanation
The \du command displays all roles in PostgreSQL along with their attributes like superuser status, create database rights, and other permissions. This is a standard psql meta-command for viewing role information. Other commands like \d or \l show different objects. Understanding roles and their attributes is essential for managing database security and access control.
In PostgreSQL 13, which command is used to switch your connection to a different database in psql?
Correct Answer:
A
Explanation
The \connect command (or \c) switches your psql session to a different database. You provide the database name as an argument. This is how you navigate between databases within a single psql session without logging out. Other meta-commands like \d or \du serve different purposes such as describing objects or listing roles.
You need to reload the PostgreSQL configuration without restarting the server. Which function should you use?
Correct Answer:
B
Explanation
The pg_reload_conf() function reloads the PostgreSQL configuration file without requiring a full server restart. This allows parameter changes to take effect for parameters that support reload. A restart would be needed for parameters that require it. This function is useful when you want to apply configuration changes with minimal downtime.
Which psql meta-command displays the structure of a specific table including columns, types, and constraints?
Correct Answer:
A
Explanation
The \d tablename meta-command displays the structure of a table including column names, data types, and constraints like primary keys and foreign keys. This helps you understand the table design. Other commands like \du shows roles or \l shows databases. The \d command is essential when working with database objects and understanding their organization.
Which PostgreSQL backup utility can create backups in custom compressed format?
Correct Answer:
A
Explanation
The pg_dump utility with the -Fc option creates backups in PostgreSQL's custom compressed format. This format offers compression which saves storage space and allows selective restoration of specific objects. Without the -Fc option, pg_dump produces plain text SQL output. The custom format is particularly useful for large databases where storage efficiency matters.
