Further adjust guidance for running vacuumdb after pg_upgrade. Since pg_upgrade does not transfer the cumulative statistics used to trigger autovacuum and autoanalyze, the server may take much longer than expected to process them post-upgrade. Currently, we recommend analyzing only relations for which optimizer statistics were not transferred by using the --analyze-in-stages and --missing-stats-only options. This commit appends another recommendation to analyze all relations to update the relevant cumulative statistics by using the --analyze-only option. This is similar to the recommendation for pg_stat_reset().
