Just turned on WAL archiving to an S3 bucket for a small database - total size of perhaps 2-4G. After turning on
achiving,we're seeing WAL logs written to S3 at the rate of about 1G every 3 minutes. That seems completely
unreasonablegiven usage of the db. I can even see that nearly nothing is happening with this:
select datname, usename, procpid, client_addr, waiting, query_start, current_query from pg_stat_activity;
Nearly every time I run that, all 20 connections have current_query = '<IDLE>'. Does current_query include inserts,
updates,and deletes or just select statements?
Any ideas what to look for or how to solve this?
