   At `cypher_clause.c:3733`, the following function is used to retrieve a node's expr:
   ```c
   ...
   Node *expr = colNameToVar(pstate, node->name, false,
                                             node->location);
   ...
   ```
   At `cypher_clause.c:4295`, the following function is used for the same purpose:
   ```c
   ...
   transform_entity *entity = find_variable(parent_cpstate, node->name);
   ...
   ```
   
   Both of them takes almost similar argument, could you tell me the difference between them?
