But we can do this better by using an incomplete struct, like
struct Query *viewQuery ...;
That way, everything has the correct type and fewer casts are required. This
technique is already used elsewhere in node type definitions.
I noticed that the examples in parsenodes.h are for structs defined within
the same file. If the struct is defined in a separate file, I guess you
might need to include another header file wherever it is used, but that
doesn't seem too bad.
No, you can leave the struct incomplete. You only need to provide its
full definition (= include the other header file) if you actually want
to access the struct's fields.
