I find it all quite confusing (and hence the above may be wrong) but
have the luxury of ignoring it as all as my users are in the same
timezone. That said, it's a useful set of abstractions as lots of
people use them regularly.
Thanks, I was aware already that "timestamp with time zone" doesn't
store any timezone contrary to what its name seems to imply. (Though
when I first started with PG some years ago, I sure fell in that trap)
