This argument is nonsense. If you want GMT, why don't you just let
initdb set it that way? It should work to set TZ=GMT in its
environment for instance.
There were a couple reasons why we made that change:
* it's fairly expensive to infer the system timezone, and people
complained about the cost of doing so on every postmaster start.
* it made timezone work more like the locale settings, which have
always been set at initdb time.
So we're not going to be reverting the change, but I am curious to find
out why you find it so important as to be willing to run a modified
version that does this the old way.
