Bruce Momjian 264c068207 This patch implements a different "relkind" ... for views. Views are now have a "relkind" of RELKIND_VIEW instead of RELKIND_RELATION. Also, views no longer have actual heap storage files. The following changes were made 1. CREATE VIEW sets the new relkind 2. The executor complains if a DELETE or INSERT references a view. 3. DROP RULE complains if an attempt is made to delete a view SELECT rule. 4. CREATE RULE "_RETmytable" AS ON SELECT TO mytable DO INSTEAD ... 1. checks to make sure mytable is empty. 2. sets the relkind to RELKIND_VIEW. 3. deletes the heap storage files. 5. LOCK myview is not allowed. :) 6. the regression test type_sanity was changed to account for the new relkind value. 7. CREATE INDEX ON myview ... is not allowed. 8. VACUUM myview is not allowed. VACUUM automatically skips views when do the entire database. 9. TRUNCATE myview is not allowed. THINGS LEFT TO THINK ABOUT o pg_views o pg_dump o pgsql (\d \dv) o Do we really want to be able to inherit from views? o Is 'DROP TABLE myview' OK? -- Mark Hollomon		26 years ago
