Right offhand this looks like a corrupt-data problem, ie, trashed length
word in some variable-length value. Autovacuum isn't particularly at
fault, it just happens to be trying to examine a value that you haven't
read lately in regular use of the database. I'd suggest seeing whether
pg_dump doesn't find the problem too; if so you'll need to start doing
data recovery.
