Hrmpf. It's a silent API breakage. The author intended to email us about it, but apparently forgot. One now needs to increment a string-pool refcount. The reason that didn't trigger a reliable crash is that there's a path where the refcount of string-pool entries aren't asserted to be above before decrementing the refcount... And that there practically never are references to the pool entries after use. Continuing to discusss whether there's a better way to deal with this. Greetings, Andres Freund
