-    Partitioned tables are not processed by autovacuum.  Statistics

+    Partitioned tables do not directly store tuples and consequently
+    autovacuum does not <command>VACUUM</command> them.  (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.
