Another question: how did you choose between using TimestampTz and
Timestamp types? I realize that internally it's all the same. Maybe
Timestamp will be slightly better since the way it is displayed
doesn't depend on the session settings. Many people I talked to find
this part of TimestampTz confusing.
timstamptz internally always store UTC.
I believe that in SQL, when operating with time in UTC, you should always use timestamptz.
timestamp is theoretically the same thing. But internally it does not convert time to UTC and will lead to incorrect use.
