+# is updated properly, especially inside triggers
+#
+# Note 1: insert into table is now the only statement which changes LIRID
+# Note 2: upon entry into before or instead of triggers,
+# LIRID is unchanged (rather than -1)
+# Note 3: LIRID is changed within the context of a trigger,
+# but is restored once the trigger exits
+# Note 4: LIRID is not changed by an insert into a view (since everything
+# is done within instead of trigger context)
