+- If you use PostgreSQL, maybe you want to add the column created_at
+  to several tables. This is only a suggestion; ejabberd doesn't use
+  that column.  Add it to your existing database executing those SQL
+  statements:
+
+ALTER TABLE users ADD COLUMN created_at TIMESTAMP NOT NULL DEFAULT now();
+ALTER TABLE rosterusers ADD COLUMN created_at TIMESTAMP NOT NULL DEFAULT now();
+ALTER TABLE spool ADD COLUMN created_at TIMESTAMP NOT NULL DEFAULT now();
+ALTER TABLE vcard ADD COLUMN created_at TIMESTAMP NOT NULL DEFAULT now();
+ALTER TABLE privacy_list ADD COLUMN created_at TIMESTAMP NOT NULL DEFAULT now();
+ALTER TABLE privacy_storage ADD COLUMN created_at TIMESTAMP NOT NULL DEFAULT now();
