Tomas Vondra 6b262f353e Document autoanalyze limitations for partitioned tables ... When dealing with partitioned tables, counters for partitioned tables are not updated when modifying child tables. This means autoanalyze may not update optimizer statistics for the parent relations, which can result in poor plans for some queries. It's worth documenting this limitation, so that people are aware of it and can take steps to mitigate it (e.g. by setting up a script executing ANALYZE regularly). Backpatch to v10. Older branches are affected too, of couse, but we no longer maintain those.
