Some commands of ALTER TABLE could fail with the following error: ERROR: "tab" is of the wrong type This error is unexpected, as all the code paths leading to ATWrongRelkindError() should use a supported set of relkinds to generate correct error messages. This commit closes the gap with such mistakes, by adding all the missing relkind combinations. Tests are added to check all the problems found. Note that some combinations are not used, but these are left around as it could have an impact on applications relying on this code. 2ed532e has done a much larger refactoring on HEAD to make such error messages easier to manage in the long-term, so nothing is needed there.
