+# Loading Extensions
+
+By default, Homebrew builds all available Contrib extensions.  To see a list of all
+available extensions, from the psql command line, run:
+  SELECT * FROM pg_available_extensions;
+
+To load any of the extension names, navigate to the desired database and run:
+  CREATE EXTENSION [extension name];
+
+For instance, to load the tablefunc extension in the current database, run:
+  CREATE EXTENSION tablefunc;
+
+For more information on the CREATE EXTENSION command, see:
