8-- adjusting the expected output.  In most cases, the queries should
9-- not find *any* matching entries.

11-- NB: run this test early, because some later tests create bogus entries.

41-- perhaps initdb forgot to scan that catalog for pinnable entries.
42-- Generally, it's okay for a catalog to be listed in the output of this
43-- test if that catalog is scanned by initdb.c's setup_depend() function;
44-- whatever OID the test is complaining about must have been added later
45-- in initdb, where it intentionally isn't pinned.  Legitimate exceptions
46-- to that rule are listed in the comments in setup_depend().
