Most of these problems are pretty trivial to solve by simply reading the manual for the database engine you happen to be using, which typically will document deviations from the standard in serviceable detail. I'd be more sympathetic to concerns about switching engines if I had, at any point in a career now heading for its 25th year, ever seen that occur.

It certainly can't be outside the top three.
