Evidently the 201x SQL standard has blindsided us twice: first by
defining a syntax for named parameters that wasn't like ours, and second
by defining a syntax for something else that conflicted with ours.
I agree that the AS approach is pretty untenable given that double
whammy, and we'd better get rid of it. (Hopefully Peter will be able
to keep us better apprised of things in the future.)
It seems that we're agreed on trying to use := instead, and the only
debate is about whether to deprecate use of => as an operator. But
anything that we might do about the latter would reach no farther than
the documentation in 9.0 anyway.
