In this tutorial article, we will learn how to implement the PostgreSQL VACUUM Command skillfully. To facilitate the process of removing dead tuples, we use the PostgreSQL VACUUM Command. So, does there exist a way to remove dead tuples altogether? And to do so is the responsibility of a Database Administrator.
Now the need arises for a healthy Database Maintainance routine to maintain the usability and efficiency of data stored in the Postgres server. Moreover, these particular rows will remain inoperable with no reliances attached whatsoever.
And dead tuples will keep on occupying the space for centuries to come. PostgreSQL characterizes these rows as “ Dead Tuples.”Īs a result, Table X’s size will keep on increasing. In normal PostgreSQL operations, until and unless the rows are not physically removed, they remain untenanted, thus, blocking up the space inside the table.
