strange bison, cannot remove reduce

hello

I am playing with methods. It's +/- function with first hidden arguments.

example: sin(10)  ~ (10).sin() is equivalent.
legal is substring('aaaa',1,3).upper() too etc

I spent some time with bison (without success).

indirection_el:                       '.' attr_name                               {
 $$ = (Node *) makeString($2);                               }                       | '.' attr_name '(' ')'
                  {                                       $$ = (Node *) makeString($2);                               }
                     | '.' attr_name '(' expr_list ')'                               {
    $$ = (Node *) makeString($2);                               }                       | '.' '*'
       {                                       $$ = (Node *) makeString("*");                               }
 
this is correct but doesn't work
postgres=# select (10).aaa.aaaa.bbbb.procedure(10);
ERROR:  syntax error at or near "("
LINE 1: select (10).aaa.aaaa.bbbb.procedure(10);                                          ^
postgres=# select (10).aaa.aaaa.bbbb.procedure();
ERROR:  syntax error at or near "("
LINE 1: select (10).aaa.aaaa.bbbb.procedure();

correct is
indirection_el:                       '.' attr_name                               {
 $$ = (Node *) makeString($2);                               }                       | '.' type_function_name '(' ')'
                           {                                       $$ = (Node *) makeString($2);
      }                       | '.' type_function_name '(' expr_list ')'                               {
                      $$ = (Node *) makeString($2);                               }                       | '.' '*'
                         {                                       $$ = (Node *) makeString("*");
     }
 

It works
postgres=# select (10).aaa(10).ajjaja(10).qqq();
ERROR:  column notation .aaa applied to type integer, which is not a
composite type

but there arebison gram.y
gram.y: conflicts: 3 reduce/reduce

Any ideas?
