Re: Further issues with jsonb semantics, documentation

I'm just skimming here, but if a jsonb_path type is being proposed,
perhaps it would be better not to have operators that take text or
text[] as second argument.  We can provide that functionality with just
functions.  For example, it will be confusing to have 

jsonb 'some json value' - '{foo,bar}'

operate too differently from

jsonb 'some json value' - json_path '{foo,bar}'

And it will be a nasty regression to have 9.5 allow
jsonb 'some json value' - '{foo,bar}'
and then have 9.6 error out with "ambiguous operator" when the json_path
thing is added.
