I think you're missing the point here; I can't control what it resolves to, since that's the job of the function overload resolution code. But I checked, and delete(hstore,$1) still resolves to delete(hstore,text) when the type of $1 is not specified, so there's no compatibility issue there that I can see. (I'm not sure I understand _why_ it resolves to that rather than being ambiguous...) >> The overhead is possibly non-negligible for reading old values, >> but old values can be promoted to new ones fairly simply >> (e.g. using ALTER TABLE).
