To create a database from a backup in postgresql, follow these steps:

  1. Make sure you have a backup file of the database you want to restore. This backup file can be created using the pg_dump command.
  2. Open a terminal or command prompt and navigate to the directory where the backup file is located.
  3. Run the following command to create a new empty database:
1
createdb -U postgres new_database_name


Replace new_database_name with the name of the new database you want to create.

  1. Restore the backup file into the newly created database using the following command:
1
psql -U postgres -d new_database_name -f backup_file.sql


Replace new_database_name with the name of the new database you created and backup_file.sql with the name of the backup file.

  1. Enter the password for the postgres user when prompted.
  2. Once the restore process is complete, you can connect to the new database and verify that the data has been successfully restored.


That's it! You have now successfully created a new database from a backup in postgresql.
