We will also learn what a tablespace is and how to create a new tablespace for PostgreSQL database to reside on. In this post we will describe how to create, delete and change a database and all of the useful options to go along with. ![]() The next step is to create and manage PostgreSQL databases and thus a post on PostgreSQL Create Database follows. If you followed my post on “ PostgreSQL Create User – Manage Users” then you successfully created your first PostgreSQL users and also assigned them desired rights and privileges. The syntax for this is very similar to the one for deleting a table.This is the next post in a series of posts about PostgreSQL and is actually a continuation from post on “ PostgreSQL Create User – Manage Users“. You can also drop the whole database, if you decide that you don't need it any more. An example of How to Drop a Table in PostgreSQL DROP TABLE phonebook ![]() If you no longer need this table, you can simply delete it.
