right.

But in your link I don't understand array (and object) equality rules. Hstore 
(and jsonb) compare function believes that arrays are equal if each 
corresponding elements of them are equal.

postgres=# select 'a=>[]'::hstore = 'a=>[]'::hstore; ?column?
---------- t
(1 row)

Time: 0,576 ms
postgres=# select 'a=>[0]'::hstore = 'a=>[0]'::hstore; ?column?
---------- t
(1 row)

Time: 0,663 ms
postgres=# select 'a=>[0]'::hstore = 'a=>[1]'::hstore; ?column?
---------- f
