I didn't realise that Postgres has ranges, thanks for that. But, even though I have a background as a pure mathematician, I strongly disagree that "[a, b) includes x" is any more explicit than "x >= a AND x < b". Given that those ranges aren't standard SQL and are much less commonly used than simple inequality operators, I'd stick with inequalities for clarity.
