pgsql: Remove hard-wired lists of timezone abbreviations in favor of - Mailing list pgsql-committers

Log Message:
-----------
Remove hard-wired lists of timezone abbreviations in favor of providing
configuration files that can be altered by a DBA.  The australian_timezones
GUC setting disappears, replaced by a timezone_abbreviations setting (set this
to 'Australia' to get the effect of australian_timezones).  The list of zone
names defined by default has undergone a bit of cleanup, too.  Documentation
still needs some work --- in particular, should we fix Table B-4, or just get
rid of it?  Joachim Wieland, with some editorializing by moi.
