In the reference page docs on your machine or at:
http://www.ca.postgresql.org/users-lounge/docs/7.1/reference/sql-set.html
I'm not sure I agree with every nuance of the recommendations for SET
DATESTYLE in that doc; in particular, the claim that DATESTYLE is really
intended only to help with porting applications is a bit misleading
imho. I'll check the wording for the upcoming release...
