Research direction

Start by reading the two 'Free port 5432' steps in .github/workflows/ci.yml (doctor and e2e/smoke jobs), then fetch the reference step from docs/examples/ci/flisk-ci.yml in flisk-sh/flisk. Swap both steps for that template: check ss -ltn for :5432 and exit 0 when free, otherwise stop and mask the postgres units and run fuser -k 5432/tcp, with no apt-get remove. Done when grep -c "apt-get remove" .github/workflows/ci.yml returns 0 and the step runs in under a second across five CI runs.

Measured

2026-11-14, step Free port 5432 in .github/workflows/ci.yml (gh run view --json jobs, last 6 successful runs): 7, 10, 8, 10, 31, 9 s (doctor job) and 25, 8, 7, 13, 10, 8 s (smoke job). That is about 30-40 % of each doctor job (17-30 s) and 5-10 % of the smoke job.

The same step in flisk-sh/flisk costs well under a second since flisk-sh/flisk#4087, and the docs template was fixed in flisk-sh/flisk#4181 (closes flisk-sh/flisk#4177).

Cause

.github/workflows/ci.yml (2 places, doctor and e2e jobs) still runs sudo DEBIAN_FRONTEND=noninteractive apt-get remove --purge -y 'postgresql*' on every job, even when nothing listens on 5432.

Proposal

Replace both steps with the template from docs/examples/ci/flisk-ci.yml in flisk-sh/flisk (check ss -ltn for :5432 and exit 0 when free; otherwise stop and mask the postgres units and fuser -k 5432/tcp; no apt purge).

Acceptance

  • The "Free port 5432" step takes under 1 s in both jobs over the next 5 runs.
  • grep -c "apt-get remove" .github/workflows/ci.yml returns 0.
