explain analyze does actually run slower than the actual query because it has
to check the time before and after each step of the query, potentially
thousands of times. If it's a disk-bound query that doesn't matter much but if
it's a cpu-bound query it can.

Yes you can use \timing. You'll have to provide more information of what
you're doing before anyone can help you.
