Unexplained disk usage in AWS Aurora Postgres

2020-08-04 Thread Chris Borckholder
Hi! We are experiencing a strange situation with an AWS Aurora postgres instance. The database steadily grows in size, which is expected and normal. After enabling logical replication, the disk usage reported by AWS metrics increases much faster then the database size (as seen by \l+ in psql). The
