Index Scan using idx_user_user_logs, idx_user_user_logs, idx_user_user_logs,
idx_user_user_logs, idx_user_user_logs, idx_user_user_logs on user_logs
(cost=0.00..5454.21 rows=2498 width=48) (actual time=0.09..0.28 rows=10
loops=1)
Index Cond: ((id_user = 10943) OR (id_user = 10942) OR (id_user = 10934)
OR (id_user = 10927) OR (id_user = 10910) OR (id_user = 10909))
Total runtime: 0.41 msec
(3 rows)
Thank you
Gaetano
PS: if I execute the query I obtain 10 rows instead of 3 that say the
explain analyze.
