-----------
Add code to identify_system_timezone() to try all zones in the zic
database, not just ones that we cons up POSIX names for.  This looks
grim but it seems to take less than a second even on a relatively slow
machine, and since it only happens once during postmaster startup, that
seems acceptable.

Is it possible to execute this at initdb time to set the default
timezone in postgresql.conf?  The user could get a message about what
timezone was selected, and be offered a --command-line-switch to select
a specific one.

Just an idea ...

But if they change the OS timezone, we need to track that on postmaster
restart.
