@rafaelweingartner @rhtyd @swill I did `push -f` tests start again, I'm
getting an error on Travis test due to duplicate field name 'size' in
`schema-40to410.sql`, but I added this changes in `schema-481to490.sql`, do you
know why is it failing?

> In some production environments there were being experimented delays in most
> of the jobs. A search for DB optimization was taken and some deficiencies
> were discovered, we can group them in 4 groups:
> * Incorrect PRIMARY key
> * Duplicate PRIMARY KEY
> * Missing indexes (Add indexes to avoid full table scans)
> * Some views query (Change view to improve account retrieval speed)
