Managing installed extensions

In the last two recipes, we showed you how to install external modules in PostgreSQL to augment its capabilities. Actually, the last recipe came in two variants, depending on whether we can use the newly introduced extension infrastructure.

In this recipe, we will show you some more capabilities offered by the extension infrastructure. Everything here applies only to PostgreSQL version 9.1 and later.

Getting ready

You only need to ensure that your PostgreSQL version is 9.1 or later.

How to do it…

postgres=# \x on
Expanded display is on.
postgres=# SELECT *
postgres-# FROM pg_available_extensions
postgres-# ORDER BY name;
