Force the TZ environment variable to be set during initdb. This is to
short-circuit the rather expensive identify_system_timezone() procedure,which we have no real need for during initdb since nothing done here dependson the timezone setting. Since we launch quite a few standalone backendsduring the initdb sequence, this adds up to a significant savings, and seemsworth doing to save developer time even though it will hardly matter to endusers. Per my report today on pgsql-hackers.
