Hi,
I'm on 9.1.3. I set auto vacuum off for some tables. I noticed one
thing: when I run manual analyze on parent table, It seems the children
tables are also analyzed. Here is the analyze log:
INFO: analyzing "public.table_parent"
INFO: "table_parent": scanned 0 of 0 pages, containing 0 live rows and
0 dead rows; 0 rows in sample, 0 estimated total rows
INFO: analyzing "public.table_parent" inheritance tree
INFO: "table_child1": scanned 11405 of 692945 pages, containing 105632
live rows and 103 dead rows; 11405 rows in sample, 10739605 estimated
total rows
INFO: "table_child2": scanned 1858 of 112866 pages, containing 35818
live rows and 0 dead rows; 1858 rows in sample, 2178974 estimated total rows
....
But when I check the table status in pgAdmin, I noticed the (auto)
analyze time of children tables was not logged. So my question here is:
should I run a separate analyze on children tables?
