What indexes are there in this table? Indexes on expressions are particularly suspect.
There are some simple btree indexes due to foreign keys, and this one, which seems as the cause for the crashes:
CREATE INDEX schedulecard_overlap_idx ON public.schedulecard USING gist (scheduletemplate_id, (period_day::integer % 7), timerange) TABLESPACE pg_default; When I drop it, the UPDATE statement gets executed without any problems. When I create the index again, the same UPDATE crashes the server. Regards, Ondřej Bouda
