Обсуждение: Setting DateStyle

I'm trying to set my datestyle automatically in postgresql.conf this
way:
datestyle = 'iso, us'

But Postgresql won't start when I do this. I get the following message
in my logfile:
FATAL 1:  'datestyle' is not a valid option name

From other examples of postgresql.conf I've looked at, this should work.
What's going on?

That will work as of PG 7.3, but not in prior releases.  (Datestyle and
a couple of other slightly-weird SET variables didn't get folded into
GUC until 7.3.)  The workaround in old releases is to set PGDATESTYLE in
the postmaster's environment, instead.
