R: [GENERAL] Postgres 9.6.1 big slowdown by upgrading 8.4.22 - Mailing list pgsql-general

I would also like to add this:

The explain analyze show that the index on that numeric field *is not* being used.
I also try to set the seqscan off but that index continues not to be used.

Maybe the problem is this?

Thank you again!
