postgresql 9.2.4 hstore search keys Unknown operator -

Can not be used? Operator Works fine with Postgresql 9.1.9 (development), fails on 9.2.4 (output)

  test = # SELECT 'a = & gt; 1, b = & gt; 2 ': hstore? | ARRAY ['B', 'C']; Error: Operator does not exist: hstore? | Text [] Line 1: Selection 'A = & gt; 1, b = & gt; 2 ': hstore? ARRAY ['B', 'C']; ^ Hint: An operator does not match given given name and logic type (fairs). You may need to explicitly enter   
 hstore is installed  
  test = create # extension extension; Error: type "hstore" already exists    
 
 
  Extension from error message Hstore  indicates that you do not actually have  extension   hstore  installed, just a few parts of it (otherwise the error message will be  The extension "hstore" already exists .) Then I suggest that you fix your hstore installation To do this, you can create unpacked  from  expansion hustore. If not, you have to do manual surgery to remove or add missing parts.
