Looked a bit into this myself, your method is quite nice compared to some things
I've seen...

+      $update_sql = "UPDATE site_settings SET value = '$escaped_value', data_type = $escaped_type WHERE name = '$escaped_setting' RETURNING 1"
+      $columns = "name, data_type, value, created_at, updated_at"
+      $values = "SELECT '$escaped_setting', $escaped_type, '$escaped_value', CURRENT_TIMESTAMP, CURRENT_TIMESTAMP"
+
+      postgresql_psql {"WITH upd AS ($update_sql) INSERT INTO site_settings ($columns) $values WHERE NOT EXISTS (SELECT * FROM upd)":
+        db => 'discourse',
+        psql_user => 'discourse',
+        unless => 'SELECT false'
+      }
+    }
+    absent: {
+      postgresql_psql {"DELETE FROM site_settings WHERE name = '$escaped_setting'":
+        db => 'discourse',
