Hi,
The index doesn't cost you so much, seq SEQ Scan actully does:
Seq Scan on isbns_a_descubrir
(cost=0.00..8067.91 rows=1 width=21) (actual time=30.044..30.044 rows=1
loops=2025)
This seq scan is called once for every row of librosdisponibilidadtemp
which passes the WHERE condition.

UNIQUE indexes? Are there any real systems that don't support indexes
