[drupal-devel] Question on use of theme_pager() and related functions

[Earl Dunovant]

The function creates its own query to count records by rewriting
yours. Usually that's fine but there are cases where it's not
accurate. When that happens there's a third parameter you can pass
that will be a query that returns the number of records you're dealing
with.
