Re: Alias hstore's ? to ~ so that it works with JDBC

tl;dr

Scala/JRuby/Clojure (any JVM-based language) + Postgres + hstore = 
awesome... why not just add a few lines to hstore--1.2.sql and make sure 
that all operators are available and indexable?

hi Andrew, hi merlin,

> use the existing "exist()" function

EXIST() can't use hstore's GiST or GIN indexes.

Since the goal is to get ? working on JDBC with indexes, I think you 
also have to do CREATE OPERATOR CLASS [1]

Best,
