-    Partitioned tables are not processed by autovacuum.  Statistics

+    Partitioned tables do not directly store tuples and consequently do not
+    require autovacuum to perform automated <command>VACUUM</command>.
+    (Autovacuum does perform <command>VACUUM</command> on table
+    partitions just like other tables.)  Unfortunately, this also means
+    that autovacuum doesn't run <command>ANALYZE</command> on partitioned
+    tables, and this can cause suboptimal plans for queries that reference
+    partitioned table statistics.  You can work around this problem by
+    manually running <command>ANALYZE</command> on partitioned tables
+    when they are first populated, and again whenever the distribution
+    of data in their partitions changes significantly.
