Hi Peter,
I strongly i agree,
I have used pg_upgrade which runs "analyze_new_cluster.sh" as post upgrade activity across all DB on cluster.
Also, I have executed manual vacuum on all individual tables. However the behavior is same until i disable the above said parameter.
Regards,
Raj

How did you upgrade?
If your upgrade involved a dump and restore, you should invoke ANALYZE
for each database (I think autovacuum will analyze all tables
eventually, but takes its time).
