Subject Re: 2.5.1 upgrade dilemma
I thought 2.5.2 behaves the same as 2.5.1 but now I'm running into sources that say that even 2.5.2 requires action when coming from a 2.5.1 database.

Is the old info still actual that I only need those constraints that are both compound and have at least one (VAR)CHAR in them without 'NOT NULL'?
