I tested this about 9 months ago, and the timestamp syntax was an issue
(due to changes in how timezones were referenced) so you'll want to
check that. I also remember some issues we had because our lead C
developer had created some functions that generated invalid sql
statements that we're accepted in 7.0.x but rejected on 7.2.x, so you'll
need to check your application for issues like that that might crop up.
I might suggest you take a look at 7.3 which, while currently in beta,
will be released within a fortnight.
