can't to remove shift/reduce

[Pavel Stehule]

Hello

I have gram file that works. But contains shift/reduce and I cannot to
correct it. What is worst, I don't see what is problem from bison log. 

columnref:      relation_name
                                {
                                }
                        | relation_name indirection
                                {
                                }
                ;

                        | '.' column_method
                                {
                                }
                        | '.' '*'
                                {
