One other point is that symlinking to system timezone info will not
cause Postgres to "pick up changes automatically". You'll probably
still need a postmaster restart to get the new settings loaded in.
If the timezone info update is delivered as part of a Postgres update,
the need for this is fairly obvious, but if it's happening as part
of an update of a seemingly unrelated package, not so much.

To me, the idea of linking to system timezone info is a convenience
for packagers, and it is (and should be) the packagers' responsibility
to determine whether it's a sane idea for their environment. If they
are competent to determine that, they are certainly competent enough
to make it happen without assistance from our configure script.
