Drupal's db_fetch_array functions use *_fetch_assoc() internally.  In ext/mysql and ext/pgsql, *_fetch_array() returns a doubly indexed array by field AND number.  *_fetch_assoc() returns just the associative array.  I have frankly never seen a reason to want the doubly indexed version, so it's good that Drupal gives you the version that makes sense. :-)

You should be opposed to using mysql_* directly, as that is the Wrong Way(tm) to access the database.  That bypasses all of the Drupal security handling and is an SQL Injection risk.

In this case, in fact, you probably don't want a fetch at all.  You just want the single count value.

$count = db_result(db_query($countsql));

And you're done.
