+# These tables are never deleted from in normal operation [*], so we can resume porting
+# over rows from a previous attempt rather than starting from scratch.
+#
+# [*]: We do delete from many of these tables when purging a room, and
+#      presumably when purging old events. So we might e.g.
+#
+#      1. Run portdb and port half of some table.
+#      2. Stop portdb.
+#      3. Purge something, deleting some of the rows we've ported over.
+#      4. Restart portdb. The rows deleted from sqlite are still present in postgres.
+#
+#      But this isn't the end of the world: we should be able to repeat the purge
+#      on the postgres DB when porting completes.
