OK, so here's a minimal reproducer:

drop table schedulecard;

create table schedulecard (
  scheduletemplate_id bigint NOT NULL,
  period_day smallint NOT NULL
);

CREATE INDEX schedulecard_overlap_idx
     ON schedulecard USING gist
     (scheduletemplate_id, (period_day::integer % 7));

insert into schedulecard values(12, 1);

update schedulecard set period_day = period_day + 7;

Interestingly, it doesn't crash if I change the index type to btree,
which I was not expecting because the crashing code seems pretty
independent of the index type.

Haven't traced further than that yet.
