Question about DB stats resets

[Luis <luisico@xxxxxxxxx>]

Hi, I have a doubt about stats reset.

I've been investigating some zero values in some tables tuples stats.
By querying pg_stat_database view I can see reset times (pg_stat_database) that have not been performed by me (doing a SELECT pg_stat_reset())

My question is, what other actions or events may reset the stats of a DB?

I don't know if, somehow, having a busy server or with a high number of DBs may produce this effect.

Thanks
