If the goal is just to use a single config and have tz match the
system, the setting localtime in the postgresql.conf should suffice.
IIRC this is what we've started doing, since we we're bit by this as
well. (I think the first systems we noticed it on were ones where
system was UTC and Postgres was GMT, which was mostly a cosmetic
problem, but it surprised us elsewhere too). It makes me wonder if
there was enough thought put into the backwards compatibility angle of
this; either what the default should be, or to make sure people were
aware of the change.
