Re: JDBC and the hstore ? operator - no longer working with build 1211

This still doesn't work completely with a PreparedStatement.

Other hstore operators that start with an ? do not work: ?& and ?|

e.g.:

connection.prepareStatement("select * from foo where hstore_column ?& array['key']");
connection.prepareStatement("select * from foo where hstore_column ?| array['key']");

The prepareStatement() call succeeds, but when calling executeQuery() an exception is thrown:

org.postgresql.util.PSQLException: No value specified for parameter 1.

The goal is to pass the array as a parameter, something like:

Array keys = con.createArrayOf("text", new String[] {"key1","key2"});
connection.prepareStatement("select * from foo where hstore_column ?& ?");
pstmt.setArray(1, keys);
ResultSet rs = pstmt.executeQuery();

Tested with 1212 and 42.0.0
