I'm wondering if there is anyway to enforce that ranges in a table be adjacent in perhaps a similar way to enforcing that they are non-overlapping.
Consider a (very simplified table)
CREATE TABLE (
thing_id int,
period tsrange,
EXCLUDE USING gist (thing_id WITH =, period WITH &&),
CHECK (lower_inc(period) and not upper_inc(period))
);
This should (I believe) enforce that all periods for a given thing are non-overlapping, and that each is lower-inclusive, upper-exclusive ranges.
I'd also like to enforce that all ranges for a given 'thing' are adjacent.
Is that possible?
Thanks,
Ben
