Re: Querying a fast subquery never returns

Note that the explain query plan is pretty much useless in this case.

We can run an explain on the inner query which runs in 14 seconds, but trying to run an explain on the whole query produces the same result: it never returns and it gets stuck on the sorting results stage.
