[SQLObject] Exceptions are unpredictable?

[Leif K-B. <eu...@ec...>]

I'm writing an application with SQLObject that uses EAFP (Easier to Ask 
for Forgiveness than Permission) style, as does most Python code. 
Unfortunately, the exceptions SQLObject raises seem to change depending 
on the database being used, which makes doing this in a cross-database 
way impossible. Would I be better off using LBYL  (Look Before You Leap) 
style with code that uses SQLObject?
