Good database software knows that if you use the aggregate function
count(*) you don't want to retrieve internally all fields of all the
involved tables.  So count(*) might even be slightly faster then count(1)
in those cases. It is not a good idea to change this behaviour to count(1).
Can you tell me which database server you using?
