wrong key type used when creating non-frozen map virtual column #5165
I'm not sure if this actually makes anything crash or work incorrectly. The virtual columns are there to check liveness, so we're only interested in timestamps in their mutations. But there is a piece of code that could serialize a text field while thinking that it's an int field, or the other way around. Maybe it could cause some undefined behavior. I tried to insert big text keys when the serialization code thought it was an int, but I didn't notice anything strange happening.
