I want to do something like this (pardon my pseudocode):

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

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:

This is probably also easy in perl and python as well.
