+# Improvements
+
+- When custom databases are created, the manifest can be used to
+  specify any PG extensions that need to be loaded via the `extensions`
+  array attribute on the database.
+  Example:
+
+```
+properties:
+  pgpool:
+    databases:
+    - name: animals
+      extensions:
+      - citext
+      - pgcrypto
+```
