Hello everyone,

Resolved, I've done:

hrs=# CLUSTER hosts_ip_idx ON hosts;
CLUSTER
hrs=#
hrs=#
hrs=# SELECT relpages * 8192 AS size_in_bytes, relname FROM pg_class
WHERE relnamespace = (SELECT oid FROM pg_namespace WHERE nspname =
'public') ORDER BY size_in_bytes DESC LIMIT 10;
size_in_bytes | relname
---------------+--------------------------------------
548864 | reservation
376832 | hosts
106496 | reservation_hosts
49152 | reservation_businessneed_idx
49152 | hosts_ip_idx
40960 | reservation_status_idx
40960 | reservation_hosts_reservation_id_idx
40960 | reservation_hosts_host_id_idx
40960 | hosts_hostname_idx
40960 | hosts_location_idx
(10 rows)

Why such a dramatic reduction in table size -- from 80MB to 0.55MB?!

I didn't add or delete many rows from that table. Quite a lot of UPDATEs
are running daily, though.

Regards,
mk
