## Summary of changes
- Use `build-tools:pinned-bookworm` whenever we download Neon artefact
## Problem
Nightly Benchmarks have been broken for some time due to various
reasons, this PR fixes it
## Summary of changes
- Pull `build-tools` image from dockerhub for `benchmarking` workflow
- Use `aws-actions/configure-aws-credentials` to upload/download
artifacts from S3
- Fix Postgres 16 installation (for pgbench)
## Problem
We use a set of **Neon** reuse databases in benchmarking.yml which are
still using pg14.
Because we want to compare apples to apples and have migrated the AWS
reuse clusters to pg16 we should also use pg16 for Neon.
## Summary of changes
- Automatically restore the test databases for Neon project
## Problem
We use infrastructure as code (TF) to deploy AWS Aurora and AWS RDS
Postgres database clusters.
Whenever we have a change in TF (e.g. **every year** to upgrade to a
higher Postgres version or when we change the cluster configuration) TF
will apply the change and create a new AWS database cluster.
However our benchmarking testcase also expects databases in these
clusters and tables loaded with data.
So we add auto-detection - if the AWS RDS instances are "empty" we
create the necessary databases and restore a pg_dump.
**Important Notes:**
- These steps are NOT run in each benchmarking run, but only after a new
RDS instance has been deployed.
- the benchmarking workflows use GitHub secrets to find the connection
string for the database. These secrets still need to be (manually or
programmatically using git cli) updated if some port of the connection
string (e.g. user, password or hostname) changes.
## Summary of changes
In each benchmarking run check if
- database has already been created - if not create it
- database has already been restored - if not restore it
Supported databases
- tpch
- clickbench
- user example
Supported platforms:
- AWS RDS Postgres
- AWS Aurora serverless Postgres
Sample workflow run - but this one uses Neon database to test the
restore step and not real AWS databases

Sample workflow run - with real AWS database clusters
https://github.com/neondatabase/neon/actions/runs/10346816389/job/28635997653
Verification in second run - with real AWS database clusters - that
second time the restore is skipped
