This updated patch contains all the intended functionality, including

I would like to not create any -> operators, so that that syntax could
be used in the future for method invocation or something similar (it's
in the SQL standard).
This is the first time I have heard that we should stay away from this.
We have operators with this name in hstore, which is why I chose it.
Have we officially deprecated '->'? I know we deprecated "=>", but I
simply don't recall anything about '->'.
I also don't find the proposed use to be very intuitive. You invented
lots of other function names -- why not invent a few more for this
purpose that are clearer?
I'm happy to take opinions about this, and I expected some bikeshedding,
but your reaction is contrary to everything others have told me. Mostly
they love the operators.
I guess that '~>' and '~>>' would work as well as '->' and '->>'.
