Alexey Kondratov 4b77807de9 fix(compute/sql_exporter): Ignore invalid DBs when collecting size (#11097)
## Problem

Original Slack discussion:

TL;DR in Postgres, it's totally normal to have 'invalid' DBs (state
after the interrupted `DROP DATABASE`). Yet, some of our metrics
collected with `sql_exporter` try to get the size of such invalid DBs.

Typical log lines:
```

```

## Summary of changes

Ignore invalid DBs in these two metrics -- `pg_stats_userdb` and
`db_total_size`

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.
