## Problem `postgres_exporter` has database collector enabled by default and it doesn't filter out invalid databases, see https://github.com/prometheus-community/postgres_exporter/blob/06a553c8166512c9d9c5ccf257b0f9bba8751dbc/collector/pg_database.go#L67 so if it hits one, it starts spamming logs ``` ERROR: [NEON_SMGR] [reqid d9700000018] could not read db size of db 705302 from page server at lsn 5/A2457EB0 ``` ## Summary of changes We don't use `pg_database_size_bytes` metric anyway, see https://github.com/neondatabase/flux-fleet/blob/5e19b3fd897667b70d9a7ad4aa06df0ca22b49ff/apps/base/compute-metrics/scrape-compute-pg-exporter-neon.yaml#L29 so just turn it off by passing `--no-collector.database`.
This directory contains files that are needed to build the compute images, or included in the compute images.
compute-node.Dockerfile To build the compute image
vm-image-spec.yaml Instructions for vm-builder, to turn the compute-node image into corresponding vm-compute-node image.
etc/ Configuration files included in /etc in the compute image
patches/ Some extensions need to be patched to work with Neon. This directory contains such patches. They are applied to the extension sources in compute-node.Dockerfile
In addition to these, postgres itself, the neon postgres extension, and compute_ctl are built and copied into the compute image by compute-node.Dockerfile.
