I like that idea as well. Someone like me who didn't know that this
feature was in there for M$ could have assumed it _was_ standard
behavior, and started using it as a habit. Then when I started porting
my code to another database, I'd have an extra surprise in for me. :)
Rather than being an option targeted at just this piece of grammer,
perhaps it could a piece of a potentially larger option of "stricter
standards compliance." I realize there are a number of useful extensions
to the SQL standard in Postgres (which I like and use.), but it seems
like there would be uses for minimizing non-standard behavior, as well.
Thank you all for your contributions to Postgres-- I use it everyday. :)
