Fixed in master - presumably by #620/#621.

Fix will be in release 1.8.10

[SpacemanPaul]

Nope, still happening. More investigation needed.

[alexgleith]

hehe, thanks @SpacemanPaul

Paul, the multidate is triggering for no reason

[SpacemanPaul]

I know, it means that data from two different dates is being returned for the query. I still can't reproduce this locally with a fresh index.

I will need a database dump.

Materialised view definitions were out of date - they include a bug that was fixed in September 2020 and released in October 2020 in 1.8.2.

Running datacube-ows-update --schema --role <db_role> fixes the issue.
