I just saw a post indicating that PostgreSQL Foreign Keys and 
Constraints are actually managed via triggers, therefore instead of 
doing a DROP TABLE CASCADE I could just disable triggers.


Is this true?


If so it 'feels' like there may be dangerous side effects, any thoughts 
on any cautions and gotcha's to this approach?


Thanks in advance

Those two things don't produce the same end result...

Why did you add constraints/foreign keys in the first place?
