Playbook for moving PostgreSQL between Kubernetes clusters or environments, especially with Crunchy Postgres Operator (PGO). Covers how to choose a method (PGO standby cluster from a pgBackRest repo or streaming, restore from backup, logical replication, dump/restore), pre-flight checks (versions, extensions, collation/glibc, sequences, roles), write freeze and cutover, data checks, rollback and the point of no return. Use whenever a task moves, clones, upgrades across clusters, or cuts over a…
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
# Playbook: Move PostgreSQL between Kubernetes clusters <!-- devops-ai-kit · Last reviewed: 2026-10-28 · Always L3. See also: `db-reliability`, `disaster-recovery`, `k8s-storage`. --> The field names of the `PostgresCluster` CR and the exact behavior change between PGO versions. Ask `infra-researcher` to check the syntax for the **exact PGO and PostgreSQL versions** before you write manifests. This playbook explains how to think about the migration and what you must not miss. ## 1. Check the source (add to recon) - [ ] Versions: PostgreSQL major / minor, PGO (source and target), Kubernetes on both clusters. - [ ] DB size, biggest tables, WAL rate (to estimate the sync time). - [ ] Extensions and their versions (`\dx` on each database). Does the target have the same extensions / versions? - [ ] Roles, ownership, grants. Which user does the app use? Which Secret holds the password? - [ ] Tables **without a primary key** (important for logical replication). - [ ] Sequences (logical replication does **not** copy sequence values). - [ ] Locale / collation: provider (libc or ICU), glibc version of the source and target images. …

How to install
mdr add hoangminhung/devops-ai-kit/playbook-pg-migration@sha256:93de63c537417c5fThe line at the top of this page pins the label git:20261028.645512f, 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.
