The really serious problem with this is the assumption that the server
has the same set of available timezones (and spellings of same) as the
client does.

I'm not sure that there is a better alternative, mind you. Just
pointing out that the emperor doesn't really have any clothes on.

In 8.0 and later you can presume that the server is following the
zic database's set of timezone names, but I dunno whether that has
anything to do with the Java universe. Pre-8.0, you'd be foolish
to assume much of anything.

It's not quite too late to make TimeZone be one of the GUC_REPORT
settings in 8.0, if that would help your problem.
