Why were you running ANALYZE on the first place? If it's just to see
how many dead space there is, I suggest you peek into
pg_stat_user_tables instead, which is less invasive. Autovacuum itself
should run ANALYZEs as needed (and you can, of course, tune it if you
feel it's not frequent enough in the default configuration).
