+ALERTA ALERTA
+
+N8N recipe is switching from deploying a PostgreSQL and setting it as the database to using the
+built-in SQLite database instead. PostgreSQL can still be enabled, see .env.sample for the
+lines to add to your configuration to enable it (should retain data that was in Postgres).
+
+There is no clean migration path between sqlite and postgres. Committing to one pretty much
+sticks you to that one (there are hacks but it is involved and incomplete).
