The fundamental issue is reserving what used to be an available operator
name, in the service of a syntax that's not got anything to recommend
it other than being Oracle-compatible.  AS is already a fully reserved
word, so we'd be taking no risk of breaking anyone's app if we use it.

And plpgsql has got nothing to do with this, because we're talking SQL
syntax not plpgsql.
