All your view and function creation statements should be in scripts that you maintain as a kind of best practice. If you've done that, then you can simply drop/cascade the view you're replacing after you renamed it and then rebuild the rest of them.
I actually go one step further and put the view creation scripts into a function: then I can just do 'SELECT RebuildViews();' at appropriate moments. This typically happens at the very end of the materialization process switcheroo I have to do if my view has to be available while the materialization is happening. Postgres 9.4 will make this technique basically obsolete with the lock-free refresh (Thanks Kevin!).

I have a view which is very slow to computer, but doesn't change often.
I'd like to materialize it. I thought I'd do a simple poor man's materialize by:
1) ALTER VIEW myview RENAME to _myview
2) SELECT * INTO myview FROM _myview
The only problem is that all my other views, which are dependent on
myview, automatically rename to _myview. That would normally be very
helpful but is exactly the opposite of what I want!
Is there a work around?
I'm running Postgres 8.3 - upgrading is a possibility but difficult.
