The only reason being that I don't want to waste space storing arbitrarily
long pieces of information.
I was not aware that TEXT is just as (in)efficient as VARCHAR, though. If
that is truly the case, I will consider using TEXT in some places, but only
when I am very careful in the INSERT and UPDATE clauses so as not to store
too long things.

So, basically:
1) There's absolutely no way to get back the 7.1.3 "silent truncation"
behavior (which is, IMO, stupid, I like the non-standard truncation behavior)
2) You have to truncate on INSERT/UPDATE and continue using VARCHAR(x)
3) Instead of 2, you can use TEXT
Several others have asked this question since 7.2 appeared but none
received a response to #1.
Thanks,
Doug
