I agree with Tom here. I have used the Oracle NOWAIT feature in the past and think it is a great feature IMHO. But when you need to use it, you want it to apply very specifically to a single statement. Using a sledge hammer when you need a tweezers isn't the right way to go.
Once I have written patches for 7.3 to implement this feature for LOCK statement. For example:
test=# LOCK TABLE sales NO WAIT; ERROR: Cannot aquire relation lock
If there's enough interest, I will modify and submit it for 7.5. -- Tatsuo Ishii

That would be great. Many people are asking for that. Maybe I have time to implement that for SELECT FOR UPDATE.
