- The column (tests/conformance/postgres_column.rs, feature `postgres`,
default-off): the factories are the alkstore pg-factory pattern reused —
`dual-tier postgres+local` (kv = postgres + large = local at the
column-declared threshold 1024, window delay `Duration::ZERO`) and
`kv-only(postgres)` at 1024 (the rejection row's host); a fresh
engine-owned schema per `open()` (unique per call, seeded per
tag/pid/time — racing opens included), registry-tracked per instance,
teardown `DROP SCHEMA IF EXISTS … CASCADE` over exactly the minted
schemas + the vended temp roots (idempotent, owned, panicking-row-safe)
- The SKIP posture: connection settings ride the environment
(ALKBLOBS_PG_HOST/PORT/USER/PASSWORD/DB), every runner gates behind a
reachability probe, server-less runs skip cleanly (a skip is not a
failure); the acceptance run is green against the harness server
(dockerized `pglo-poc`, :15432 — the alkstore harness's same server)
- Rows: the form-independent reference rows mirror verbatim (INV-1,
INV-6, the NoLivenessSources/ProtectFailed abort shapes, the kv-only
rejection row); the sqlite column's durable-schedule sweep family
mirrors (schedule-relative INV-2/INV-3 readings, the two-sweep exact
counts over the full protection set, the race across the window
delay, the holder-stages-only lease shape, INV-5 list correctness);
the dispatch rows adapt the placement oracle by medium (independent-
connection counts of the schema's rows vs the root's committed files)
plus the virgin-store row; every row ADR-stamped, traced to the
backlog
- Structural factory tests: fresh isolated opens (two opens mint
distinct schemas and share nothing) and teardown against a panicking
row (schemas really dropped, pg_namespace-verified)
- README amended: the postgres rows table in §Columns beyond the
reference set; the column plan's SKIP-posture note names the landed
column; current state (four columns, waves 2–4)
Verification: cargo test (default) 69/19/3 ok — the column compiles
out; cargo test --features postgres 102/36/3 ok against the harness
server (and green skipping server-less); cargo clippy --all-targets --
-D warnings green (default, postgres, all-features); cargo fmt --check
green; pg_namespace verified schema-clean after live runs.
