Well, as said upthread, the argument for not changing would be that it
would make it easier to dump views and reload them into older PG versions.
I'm not sure how big a consideration that is, or whether it outweighs
possible cross-DBMS compatibility benefits of dumping the more standard
syntax.  Presumably we are going to change it at some point; maybe we
should just do it rather than waiting another 5 years.

IOW, I guess I lean mildly towards changing, but I've been beaten up
enough lately about backwards-compatibility worries that I'm not going
to fight for changing this.
