Thanks.

how about  the case as follows?

idx_scan = 0 and idx_tup_read = 0 and idx_tup_fetch = 0, but
idx_blks_read is not 0 and idx_blks_hit is not 0
?

regards

Hi,

Below query can be handy to find unused indexes.

select indexrelname from pg_stat_user_indexes where idx_scan = 0 and idx_tup_read = 0 and idx_tup_fetch = 0 ;

Hope it helps.
