Thank you Ron! I was quite sure 0.1 meant 1/1000 because of this:

SELECT min_val,max_val FROM pg_settings WHERE name = 'autovacuum_analyze_scale_factor' \gx

-[ RECORD 1 ]
min_val | 0
max_val | 100


I will adjust the values accordingly and check back. Cheers!

Dimitris

"Specifies a fraction of the table size to add to
autovacuum_analyze_threshold when deciding whether to trigger an ANALYZE.
The default is 0.1 (10% of table size)."
