-- Check that system tables can be reindexed.

-- Note that this test currentlyhas to run without parallel tests

--being scheduled, as currentlyreindex catalog tables can cause

-- Note that this test currentlyis not included in the default

--schedules, as currentlyreindexing catalog tables can cause

-- deadlocks:

--

-- * The lock upgrade between the ShareLock acquired for the reindex

-- tables are routinely released before commit - therefore the lock

-- held for reindexing doesn't guarantee that no running transaction

-- performed modifications in the table underlying the index.

--

-- This is particularly problematic as such conflicts can be

-- triggered even when run in isolation, as a previous session's

-- temporary table cleanup might still be running (even when the

-- session ended from a client perspective).

-- Check reindexing of whole tables

REINDEX TABLE pg_class; -- mapped, non-shared, critical

REINDEX TABLE pg_index; -- non-mapped, non-shared, critical

# These depend on the above two
