I'm trying to simplify a schema, where I had many ranges floating around. My idea is to put them all in an array field and query like this:
SELECT
event.*
FROM event
JOIN participant_details
USING (participant_id)
WHERE
tsrange(event.start, event.end) && ANY (participant_details.periods);
periods is tsrange[].
I've tryed and it worked, but without indexes. I've tried something, but didn't found anything... Does someone know how to index this kind of field (tsrange[])?
From the docs I learn that there is some GIST magic, but I would need to code in C. Is that true?
