thanks for the
INJECTION_POINT("typecache-before-rel-type-cache-insert");
Now I have better understanding of the whole changes.
+/*

+ * entries, marked as in-progress by lookup_type_cache(). It may happen
+ * in case of an error or interruption during the lookup_type_cache() call.

+static void
+finalize_in_progress_typentries(void)
comment typo. "TypeCacheHas" should be "TypeCacheHash"
