Not really, I would expect roughly double execution time, not an
exponential increase. Still not experienced enough to diagnose with
what has been provided but I will suggest you provide the version that
you are running these queries against and confirm that the results are
consistent across multiple runs to discount the possibility that
locking or other transient work is involved.
Curious if increasing work_mem helps but its mostly a trial-and-error
thing for me (I wouldn't expect it to)...
