Tom Lane 0af83bd530 Add new timezone abbrevation "FET".
This seems to have been invented in 2011 to represent GMT+3, non daylight
savings rules, as now used in Europe/Kaliningrad and Europe/Minsk.
There are no conflicts so might as well add it to the Default list.
Per bug #7804 from Ruslan Izmaylov.

Timezone
========

This is a PostgreSQL adapted version of the timezone library from
http://www.iana.org/time-zones

The source code can be found at:

	ftp://ftp.iana.org/tz/releases/tzcode*.tar.gz

The data files under data/ are an exact copy of the latest data set from:

	ftp://ftp.iana.org/tz/releases/tzdata*.tar.gz

Since time zone rules change frequently in some parts of the world,
we should endeavor to update the data files before each PostgreSQL
release.

At each update, we should check if time zone offsets have changed.
Just search for the current or previous year and see what has changed.
Sometimes a country changes its time zone offsets, for example Georgia
in 2004.  Just grepping in the zic database files for 2004 is enough to
spot such a change.  Then the files under tznames/ should be updated.
