This enumeration type is used only by the function find_item_in_list
to return the info on how an item has been resolved against a list
of possibly aliased items.
The item can be resolved:
- against an alias name of the list's element (RESOLVED_AGAINST_ALIAS)
- against non-aliased field name of the list (RESOLVED_WITH_NO_ALIAS)
- against an aliased field name of the list (RESOLVED_BEHIND_ALIAS)
- ignoring the alias name in cases when SQL requires to ignore aliases
(e.g. when the resolved field reference contains a table name or
when the resolved item is an expression) (RESOLVED_IGNORING_ALIAS)
