Detect which gbrain engine is in use (PGLite vs Postgres), prefer Postgres for agent-harness installs, install/provision Postgres (Supabase discovery via SUPABASE_ACCESS_TOKEN, local Postgres, opt-in Docker), and move an existing PGLite brain to Postgres with its history (plan, ask, run). Detection is one engine-free command; the install ladder is one flag.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Postgres Adopt > The engine is the brain's foundation: PGLite is the zero-config floor, > Postgres is where concurrency, multi-machine access, and 1000+ pages live. > This skill answers "which one am I on?", prefers Postgres when the > operator wants it, and moves data safely — never by flipping config. ## Contract This skill guarantees: - Detection is engine-free and read-only: `gbrain engine status --json` answers with the database down (that is the point of the command). - Engine changes NEVER happen by editing config. A PGLite brain moves with `gbrain migrate --to postgres` (alias `--to supabase`), which graduates it: plan first (exit 3), run only with the user's `--yes --expect <plan_hash>`, verify every table, then flip routing. This skill wraps it; it never reimplements it. - The target URL never appears in a command, transcript or output: it lives in `GBRAIN_TARGET_URL` and every command uses `--url-env GBRAIN_TARGET_URL`. - Provisioning consent is explicit: the docker rung needs `--allow-docker`, creating a database on a local server needs `--allow-create-db`. Headless mutation of infrastructure the operator didn't opt into never happens. …

How to install
mdr add garrytan/gbrain/postgres-adopt@sha256:8cf801e2e0d29da5The line at the top of this page pins the label git:20261007.590bb9a, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
