I have never experienced that problem.
I only update production machines during scheduled maintenance periods
though, where the database is taken offline, a dump is made, then it
updated. If there is a problem, it can be restored from the dump. Never
been a problem for me though - but taking a dump of the database first
is generally a good idea.
