How to view the number of rows in a PostgreSQL database?

You can use the following command to view the number of rows in a table in a PostgreSQL database:

SELECT COUNT(*) FROM table_name;

Replace table_name with the name of the table for which you want to view the number of rows.

For example, to view the number of data rows in a table named users, you can run the following command:

SELECT COUNT(*) FROM users;

This command will return the number of rows in the table users.
