Hi,
I'm interested in learning more about the guarantees/semantics of pg_stats. For example, is there a guarantee that the n_distinct and most_common_vals fields will take into account any values appearing more than M times or maybe with frequence more than f? In what cases will n_distinct and most_common_vals will miss some values?
Any pointers to documentation or source code would be greatly appreciated.
Best,
Stefanos
