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.

If so, you could use PL/R:
