ALTER TABLE (and ALTER VIEW, ALTER SEQUENCE, etc.) now use a RangeVarGetRelid callback to check permissions before acquiring a table lock. We also now use the same callback for all forms of ALTER TABLE, rather than having separate, almost-identical callbacks for ALTER TABLE .. SET SCHEMA and ALTER TABLE .. RENAME, and no callback at all for everything else. I went ahead and changed the code so that no form of ALTER TABLE works on foreign tables; you must use ALTER FOREIGN TABLE instead. In 9.1, it was possible to use ALTER TABLE .. SET SCHEMA or ALTER TABLE .. RENAME on a foreign table, but not any other form of ALTER TABLE, which did not seem terribly useful or consistent. Patch by me; review by Noah Misch.
