Bug reference:      12537
Logged by:          Endrigo Antonini
Email address:      eantonini@eidoscode.com
PostgreSQL version: 9.3.5
Operating system:   CentOS 6.5
Description:

It is not possible to configure postgresql server to use the same timezone
of the server. It is necessary that the postgres use the same timezone as
the server.
Today, each time I change the timezone of the server, I have to change the
timezone the configuration file of the postgresql. It's necessary to be
possible to configure it to use servers timezone.

According to the docs, there is no way to have log_timezone default to
the OS timezone:

        Sets the time zone used for timestamps written in the server log.
        Unlike <xref linkend="guc-timezone">, this value is cluster-wide,
        so that all sessions will report timestamps consistently.
        The built-in default is <literal>GMT</>, but that is typically
        overridden in <filename>postgresql.conf</>; <application>initdb</>
        will install a setting there corresponding to its system environment.
        See <xref linkend="datatype-timezones"> for more information.
        This parameter can only be set in the <filename>postgresql.conf</>
        file or on the server command line.

I suppose you could modify the Postgres server start script to set
log_timezone based on some OS setting though.
