In this recipe, we will show you how to use pgAdmin for the administration of your database. PgAdmin is one of the two graphical interfaces that we introduced in the Using graphical administration toolsrecipe in Chapter 1, First Steps; the other one is OmniDB, to which we dedicate this next recipe.
You should have already installed pgAdmin as part of the Using graphical administration toolsrecipe from Chapter 1, First Steps, which includes website pointers. If you haven't done so, please read it now.
Remember to install pgAdmin 4, which is the last generation of the software; the previous one, pgAdmin 3, is no longer supported and hasn't been for a few years, and will give various errors on PostgreSQL 10 and above.
