I test it in the first time :)
With the 'order by' it works well, but in 'theory' if you
run sequentially and physically a table, you expect obtain the same
results with a same query.
There is no indexes that can intersect the results or inherits
tables.
But with the option synchronize_seqscans in off, it works like
i expected :)
i will study a bit more this option on monday (like always).
