pgsql: Update timezone code to track the upstream changes since 2003. - Mailing list pgsql-committers

Log Message:
-----------
Update timezone code to track the upstream changes since 2003.  In particular
this adds support for 64-bit tzdata files, which is needed to support DST
calculations beyond 2038.  Add a regression test case to give some minimal
confidence that that really works.
