> Actually, if you submit a patch that says either "SCROLL is the
default"> or "NO SCROLL is the default", it will be rejected as incorrect. The> reason is that the default behavior is different from either of these,> as is explained in the NOTES section.Ok, so *that's* where the bit about the query plan being simple enough.Based on that, ISTM that it should be premissable for us to decide thata cursor requiring a sort isn't "simple enough" to support SCROLL.In any case, here's a patch that makes the non-standard behavior easierfor people to find.Jim C.
