Doc: clarify n_distinct_inherited setting There was some confusion around how to adjust the n_distinct estimates for partitioned tables. Here we try and clarify that n_distinct_inherited needs to be adjusted rather than n_distinct.
Also fix some slightly misleading text which was talking about table size rather than table rows, fix a grammatical error, and adjust some text which indicated that ANALYZE was performing calculations based on the n_distinct settings. Really it's the query planner that does this and ANALYZE only stores the overridden n_distinct estimate value in pg_statistic. Author: David Rowley <[email protected]> Reviewed-by: David G.
