Do you know how can I check if the storage method has changed?
I was thinking that the priority target of a vacuum operation is to reclaim disk space
- this might imply that the performance are worst for a seqscan - maybe it's normal.
Anyway, I am doing a VACUUM FULL ANALYZE right now to see if things get better.
Thanks for you hints
