## 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`promote-compatibility-data` job got broken and slightly outdated after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.
