[GENERAL] Would an index benefit select ... order by?

[rihad]

Hi,

Should an index be used on a created_at timestamp column if you know you 
will be using "ORDER BY created_at ASC|DESC" from time to time?

Thanks.

TIP 9: In versions below 8.0, the planner will ignore your desire to
      choose an index scan if your joining column's datatypes do not
      match
