We haven't had a fixed limit on rule recursion depth since 7.3 ...

but the documentation still said so.

     The query trees generated from rule actions are thrown into the
     rewrite system again, and maybe more rules get applied resulting
     in more or less query trees.
-    So the query trees in the rule actions must have either a different command type
-    or a different result relation, otherwise, this recursive process will end up in a loop.
-    There is a fixed recursion limit of currently 100 iterations.
-    If after 100 iterations there are still update rules to apply, the
-    rule system assumes a loop over multiple rule definitions and reports
-    an error.
+    So a rule's actions must have either a different
+    command type or a different result relation than the rule itself is
+    on, otherwise this recursive process will end up in an infinite loop.
+    (Recursive expansion of a rule will be detected and reported as an
+    error.)
