## Problem
One of the PRs opened by a `neondatabase` org member got labelled as
`external` because the `gh api` call failed in the wrong way:
```
Get "https://api.github.com/orgs/neondatabase/members/<username>": dial tcp 140.82.114.5:443: i/o timeout
is-member=false
```
## Summary of changes
- Check that the error message is expected before labelling PRs
- Retry `gh api` call for 10 times in case of unexpected error messages
- Add `workflow_dispatch` trigger
Sometimes, the benchmarks fail to start up pageserver in 10s without any
obvious reason. Benchmarks run sequentially on otherwise idle runners.
Try running `sync(2)` after each bench to force a cleaner slate.
Implement this via:
- SYNC_AFTER_EACH_TEST environment variable enabled autouse fixture
- autouse fixture seems to be outermost fixture, so it works as expected
- set SYNC_AFTER_EACH_TEST=true for benchmarks in build_and_test
workflow

## Problem
`promote-compatibility-data` job got broken and slightly outdated after
- https://github.com/neondatabase/neon/pull/8552 -- we don't upload
artifacts for ARM64
- https://github.com/neondatabase/neon/pull/8561 -- we don't prepare
`debug` artifacts in the release branch anymore
## Summary of changes
- Promote artifacts from release PRs to the latest version (but do it
from `release` branch)
- Upload artifacts for both X64 and ARM64
`safekeeper::random_test test_random_schedules` debug test takes over 2
minutes to run on our arm runners. Running it 6 times with pageserver
settings seems redundant.
Part of #8130, closes#8719.
## Problem
Currently, vectored blob io only coalesce blocks if they are immediately
adjacent to each other. When we switch to Direct IO, we need a way to
coalesce blobs that are within the dio-aligned boundary but has gap
between them.
## Summary of changes
- Introduces a `VectoredReadCoalesceMode` for `VectoredReadPlanner` and
`StreamingVectoredReadPlanner` which has two modes:
- `AdjacentOnly` (current implementation)
- `Chunked(<alignment requirement>)`
- New `ChunkedVectorBuilder` that considers batching `dio-align`-sized
read, the start and end of the vectored read will respect
`stx_dio_offset_align` / `stx_dio_mem_align` (`vectored_read.start` and
`vectored_read.blobs_at.first().start_offset` will be two different
value).
- Since we break the assumption that blobs within single `VectoredRead`
are next to each other (implicit end offset), we start to store blob end
offsets in the `VectoredRead`.
- Adapted existing tests to run in both `VectoredReadCoalesceMode`.
- The io alignment can also be live configured at runtime.

## Problem
We want to run our regression test suite on ARM.
## Summary of changes
- run regression tests on release ARM builds
- run `build-neon` (including rust tests) on debug ARM builds
- add `arch` parameter to test to distinguish them in the allure report
and in a database
## Problem
The default Postgres version is set to 15 in code, while we use 16 in
most of the other places (and Postgres 17 is coming)
## Summary of changes
- Run `benchmarks` job with Postgres 16 (instead of Postgres 14)
- Set `DEFAULT_PG_VERSION` to 16 in all places
- Remove deprecated `--pg-version` pytest argument
- Update `test_metadata_bincode_serde_ensure_roundtrip` for Postgres 16
## Problem
We want to store Nightly Replication test results in the database and
notify the relevant Slack channel about failures
## Summary of changes
- Store test results in the database
- Notify `on-call-compute-staging-stream` about failures
## Problem
`secrets.GITHUB_TOKEN` (with any permissions) is not enough to get
a user's membership info if they decide to hide it.
## Summary of changes
- Use `secrets.CI_ACCESS_TOKEN` for `gh api` call
- Use `pull_request_target` instead of `pull_request` event to get
access to secrets
## Problem
A bunch of small fixes and improvements for CI, that are too small to
have a separate PR for them
## Summary of changes
- CI(build-and-test): fix parenthesis
- CI(actionlint): fix path to workflow file
- CI: remove default args from actions/checkout
- CI: remove `gen3` label, using a couple `self-hosted` +
`small{,-arm64}`/`large{,-arm64}` is enough
- CI: prettify Slack messages, hide links behind text messages
- C(build-and-test): add more dependencies to `conclusion` job
## Problem
It's recommended that a couple of additional RUSTFLAGS be set up to
improve the performance of Rust applications on AWS Graviton.

Note: Apple Silicon is compatible with neoverse-n1:
```
$ clang --version
Apple clang version 15.0.0 (clang-1500.3.9.4)
Target: arm64-apple-darwin23.6.0
Thread model: posix
InstalledDir: /Applications/Xcode_15.4.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin
$
$ clang --print-supported-cpus 2>&1 | grep neoverse-
neoverse-512tvb
neoverse-e1
neoverse-n1
neoverse-n2
neoverse-v1
neoverse-v2
```
## Summary of changes
- Add `-Ctarget-feature=+lse -Ctarget-cpu=neoverse-n1` to RUSTFLAGS for
ARM images
## Problem
During `Run rust tests` step (for debug builds), we accidentally rebuild
neon twice (by `cargo test --doc` and by `cargo nextest run`).
It happens because we don't set `cov_prefix` for the `cargo test --doc`
command, which triggers rebuilding with different build flags, and one
more rebuild by `cargo nextest run`.
## Summary of changes
- Set `cov_prefix` for `cargo test --doc` to prevent unneeded rebuilds
## Problem
`author_association` doesn't properly work if a GitHub user decides not
to show affiliation with the org in their profile (i.e. if it's private)
## Summary of changes
- Call
`/orgs/ORG/members/USERNAME` API to check whether
a PR/issue author is a member of the org
## 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
