Comment (by robe):

 Replying to [comment:3 dracos]:
 > Hi robe, thanks for looking. I do still have the old. Swapping the order
 round gives the same query plan and execution time on both 9.6 and 13. If
 I leave out the explicit index part, then on PostgreSQL 13 it makes no
 difference (as you'd hope), but on PostgreSQL 9.6 it makes the query take
 many minutes to run, because it doesn't use the index automatically.

 So execution time, with && and ST_CoveredBy (does that make the 13 faster
 or the 9.6 slower?)
