At the very end of the installation, you should have the output displayed which indicates that all the packages were successfully installed. The command installs the PostgreSQL server and client alongside other dependencies. Type 'Y' and hit ENTER every time you are prompted to import the GPG key. $ sudo dnf install -y postgresql15-server Once the default module is disabled, proceed and install PostgreSQL 15 client and server as shown. Next, disable the default module which, as we saw earlier, is PostgreSQL 10.
Simply run the following command to achieve this: $ sudo dnf update -y With the PostgreSQL YUM repository in place, the next step is to update repositories. Step 2: Install PostgreSQL 15 on Rocky/Alma Linux To install the latest PostgreSQL version, we need to, first, install the PostgreSQL YUM repository on our system as shown. Use the INSERT INTO statement to add data in the following format: INSERT INTO table (column_name1, column_name2, column_name3) VALUES ( 'value1', 'value2', 'value3') įor example, add a row of data to the hotel table that you created above.From the output, we can clearly see that the default PostgreSQL stream – marked with is PostgreSQL 10. Once your table structure is ready, you can add some data to an existing table. where the table name is hotel, and columns are hotel_id, star, paint, location, and date with their respective lengths and column constraints. Location varchar( 25) check ( location in ( 'north', 'south', 'west', 'east', 'northeast', 'southeast', 'southwest', 'northwest')), are the column names, col_type is the type of column, and field_length is the size of the data structures to make the values more robust.įor example, you can create a table hotel with the following columns: CREATE TABLE hotel (
where table_name is the desired name set by the user, column_name1, column_name2, etc. The basic syntax to add fields in the new table is quite simple. Let’s create a new table to store some data. Note that you need to be logged in as the postgres system user to issue administrative commands. To create a new database within PostgreSQL, use the following command: createdb databasename Log in as the new user using the -i and -u flags.
