Hmm. I'd rather have it do something useful in terms of test coverage rather than being just an empty skull. How about adding the same kind of coverage as dummy_index_am with a couple of reloptions then? That can serve as a point of reference when a table AM needs a few custom options. A second idea would be to show how to use toast relations when implementing your new AM, where a toast table could be created even in cases where we did not want one with heap, when it comes to size limitations with char and/or varchar, and that makes for a simpler needs_toast_table callback. -- Michaxel
