I think it mostly means that you shouldn't use timestamp without time zone.
Or else you should use a time zone setting that doesn't involve DST.
Throwing away the time zone information is bad, because YYYY-MM-DD
HH:MM:SS doesn't uniquely identify a point in time, even if you know
what time zone it's relative to. That combination of years, minutes,
days, hours, minutes, and seconds can occur twice, if it's near a DST
boundary.
