You can also create a batch file that distributes source data to multiple destination folders , in which case you can use the file type as a selection criterion. To do this, you need a for loop , which allows a command to run repeatedly with a variable argument:. The PostgreSQL database management system, also known to many as Postgres, has many decades of development behind it.
It originally started as a project at Berkeley University in California. Today, the open source database continues to defy solutions from commercial competitors, since the development team is constantly working on its functionality and performance. But what exactly is PostgreSQL? For USB sticks to work as storage media, they need to have their own file system. Without this, it can be added manually by formatting the flash drive. Read this tutorial article to find out what the individual steps are and which file systems are available to use.
