After a VACUUM FULL ANALYZE:
portaportese=# explain analyze SELECT * FROM utente where luogorilasciodoc='ciao';
QUERY PLAN
--------------------------------------------------------------------------------------

Seq Scan on utente (cost=0.00..41329.21 rows=154 width=724) (actual
time=91.61..751.28 rows=15 loops=1)
Filter: (luogorilasciodoc = 'ciao'::bpchar)
