I'm trying to grasp the following sentence from https://www.postgresql.org/docs/9.5/static/sql-analyze.html
The autovacuum daemon, however, will only consider inserts or updates on the parent table itself when deciding whether to trigger an automatic analyze for that table. If that table is rarely inserted into or updated, the inheritance statistics will not be up to date unless you run ANALYZE manually.
Since partitioning is usually implemented through inheritance, initially, I thought this sentence implies that, being the master table empty in a partitioned table, autovacuum would never trigger an automatic ANALYZE on the whole partitioned table (including all children) leaving the planner with no statistics at all for the partitions.
On the other hand, "that table" seems to refer only to the parent table (master). If this second reading is correct, autovacuum does trigger ANALYZE automatically on the children tables and, obviously, ignores the parent, empty table. There would be no need to run ANALYZE manually in this case.
Which of the two interpretations is the right one?
