The hstore(text,text) function replaces that.

That's pretty hard to believe, because 9.5 disallows => as an operator
name altogether.

I still suspect that you have got a search path problem. You might
try, eg, "\do ||" in psql and see whether hstore || is listed or not.
Also check which schema \dx says the hstore extension is in in each
database.
