Um, that makes my head hurt:) Questions:

1) Are the basic complete budgets and the sub-budgets and super budgets existing in the same table?

2) Depending on answer to 1, to prevent overlap could you not use a form of the example here?:

https://www.postgresql.org/docs/12/rangetypes.html#RANGETYPES-CONSTRAINT

CREATE TABLE reservation (
    during tsrange,
    EXCLUDE USING GIST (during WITH &&)
);

same table.
overlap is allowed but only when it is complete containment, which is the whole point of this thread.


I finally got it. Unfortunately that does not mean I have solution.
