   > For example, explain select * from values (generate_series(1, 100000)); 
will take 8s to complete in my machine.
   
   
   FWIW this now takes 0.078s
   
   ```sql
   > explain select * from values (generate_series(1, 100000));

   1 row(s) fetched.
   Elapsed 0.078 seconds.
   ```
   
   That is still not ideal, but it seems ok for now
   
   
   @lewiszlw could you file a new ticket with a reproducer if something is 
still not working for you?
