Given postgres 11.
I'm looking for statistics on how often a particular table gets something inserted/updated/deleted.
There's of course this: https://www.postgresql.org/docs/11/monitoring-stats.html
n_tup_ins bigint Number of rows inserted n_tup_upd bigint Number of rows updated (includes HOT updated rows) n_tup_del bigint Number of rows deleted n_tup_hot_upd bigint Number of rows HOT updated (i.e., with no separate index update required)
This gives the absolute number, but not the frequency or growth over time.
Does something like that exist or will I have to make that myself?
