+-- MISC_SANITY
+-- Sanity checks for common errors in making system tables that don't fit
+-- comfortably into either opr_sanity or type_sanity.
+--
+-- Every test failure in this file should be closely inspected.
+-- The description of the failing test should be read carefully before
+-- adjusting the expected output.  In most cases, the queries should
+-- not find *any* matching entries.
+--
+-- NB: run this test early, because some later tests create bogus entries.
+
+
+-- **************** pg_depend ****************
+
+-- Look for illegal values in pg_depend fields.

+      deptype NOT IN ('a', 'e', 'i', 'n', 'x', 'P', 'S');

+-- Look for illegal values in pg_shdepend fields.

+-- **************** pg_class ****************
+
+-- Look for system tables with varlena columns but no toast table. All
+-- system tables with toastable columns should have toast tables, with
+-- the following exceptions:
+-- 1. pg_class, pg_attribute, and pg_index, due to fear of recursive
+-- dependencies as toast tables depend on them.
+-- 2. pg_largeobject and pg_largeobject_metadata.  Large object catalogs
+-- and toast tables are mutually exclusive and large object data is handled
+-- as user data by pg_upgrade, which would cause failures.
