the query that I used to fetch products was:
select * from availability
where ('27-03-2018' between start_date and end_date)
and ('31-03-2018' between start_date and end_date);
I added another column named during of type daterange and I created a
gist index :
create index idx on availability(during);
That creates a b-tree index.
Also, what did you set `during` to?
select * from availability
where during @> daterange(''27-03-2018', '31-03-2018');
With a table of 15M rows I got an execution time of 1 minute.
What was the query plan? Did you confirm that it used the index?
