Обсуждение: Problem with COPY and DateStyle

I just found out that datestyle affects the output of COPY, and hence
pg_dump:
test=> create table test(x date);CREATE    test=> insert into test values ('2001-07-31');INSERT 17239 1test=> set
datestyleto 'postgres, dmy';SETtest=> copy test to '/tmp/x';COPYtest=> \!cat /tmp/x31-07-2001test=> set datestyle to
'postgres,mdy';SETtest=> copy test to '/tmp/x';COPYtest=> \!cat /tmp/x07-31-2001
 

Should we set the datestyle at the top of pg_dump files like we do with
encoding and other settings?   Seems we should.

Never mind.  I found out that pg_dump already does a SET datestyle =
'ISO' before dumping, so all the dates are in ISO format.

I just need to mention that COPY honors Datesyle.

That was dealt with quite a while back.
