pgpass hostname and IP address

[Ron Johnson <ron.l.johnson@xxxxxxx>]

(8.4 and 9.2, but soon to 9.6)

If we sometimes access a db server by IP address, and sometimes by hostname, 
must we have two entries for each server+user (one with the hostname and the 
other with IP address), or is there a way to put them both on the same line?
