I want to do something like this (pardon my pseudocode): A=ARRAY[4, 5, 6, 7, 8] B=ARRAY[5, 6] is_sliceof(A, B), i.e., there exists a slice of A that equals B. My best thought ATM is to convert both to strings and use pattern matching - any better ideas?
I can't think of a really good way to do that directly in Postgres, but I'd bet (still not sure though) there is a way in R.
