Hi all. We see such errors on one of our own (non-system) tables on 
Postgres 10.3. They stop both automatic vacuum & automatic analyze not 
only on that table, but on all tables & databases (manual vacuuming 
works though). Luckily it's a small (but important) table - less than 
1000 rows. Any quick way of fixing it with no downtime? Thanks.
