Select Distinct in Rails Associations #69

Looks like SELECT DISTINCT doesn't work if you try to include the hstore field in the query, ie:

=> SELECT DISTINCT "services".* FROM "services";
ERROR: could not identify an equality operator for type hstore

Rails executes SELECT DISTINCT on a joined modeles when I am trying to destroy an instance which is associated (by habtm in my case).

Is this known issue? Is there an easy workaround?
