The following bug has been logged on the website:
Bug reference: 16521
Logged by: klaudie willis
Email address: klaudie(dot)willis(at)protonmail(dot)com
PostgreSQL version: 13beta1
Operating system: Windows
Description:
From documentation: "while n_distinct_inherited affects the statistics
gathered for the table plus its inheritance children"
However, as my own experience has shown me, and as illustrated here:
https://www.db-fiddle.com/f/d2ckNd9eyrGAwvdkr8H5i/0 I cannot see that
"_n_distinct_inherited" affects child partitions when set on the main
partition table. Am I missing something really simple here?
best regards
Klaudie
