Hi,
Right now there's no easy way to use the compiler to ensure that all
places that need to deal with all kinds of relkinds check a new
relkind. I think we should make that easier by moving RELKIND_* to an
enum, with the existing letters as the value.
Obviously we cannot really do that for FormData_pg_class.relkind, but
switch() statements can easily cast that to RelationRelkind (or whatever
we name it).
Does anybody see a reason not to do so?
Greetings,
Andres Freund
