Why is it useful?
Who would benefit from this IDEA? As a customer I want to be able to identify obsolete views in servers and recompile them. Currently, we use nz_check_views script to do that.
How should it work?

Purpose: Check each VIEW to make sure it is not obsolete (and in need of rebuilding).

This script operates by issuing the following SQL against each view
select count(*) from <viewname> limit 0;

The purpose of the "limit 0" is to
o parse the VIEW/query to make sure it is valid
o whlie keeping it from actually running (down on the SPUs)

What types of actions can cause a view to become obsolete and need rebuilding?
