## 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

How to reproduce benchmark results / run these benchmarks interactively.
|
|
|
|
1. Get an EC2 instance with Instance Store. Use the same instance type as used for the benchmark run.
|
|
2. Mount the Instance Store => `neon.git/scripts/ps_ec2_setup_instance_store`
|
|
3. Use a pytest command line (see other READMEs further up in the pytest hierarchy).
|
|
|
|
For tests that take a long time to set up / consume a lot of storage space,
|
|
we use the test suite's repo_dir snapshotting functionality (`from_repo_dir`).
|
|
It supports mounting snapshots using overlayfs, which improves iteration time.
|
|
|
|
Here's a full command line.
|
|
|
|
```
|
|
RUST_BACKTRACE=1 NEON_ENV_BUILDER_USE_OVERLAYFS_FOR_SNAPSHOTS=1 DEFAULT_PG_VERSION=16 BUILD_TYPE=release \
