## 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
