Migrate PostgreSQL clusters from the Zalando postgres-operator (acid.zalan.do postgresql CRs, Spilo/Patroni, WAL-G) to CloudNativePG (CNPG) on Kubernetes, incl. fully air-gapped clusters. Core knowledge: the two walls (Spilo↔CNPG glibc/collation divergence that corrupts physically-copied indexes; WAL-G↔Barman archive incompatibility that strands old backups), three migration paths (logical replication default; initdb.import for small DBs/PG≤13; pgbasebackup as the discouraged same-major exception), the acid.zalan.do→Cluster manifest field map with no-equivalent gaps (preparedDatabases, sidecars, logical-backup cron), backup re-plumbing onto the barman-cloud CNPG-I plugin, HA parity (synchronous + failoverQuorum vs Patroni failsafe), consumer cutover (service/secret renames, scram, cnpg metrics), air-gap mirroring, stay-vs-migrate evidence.

Quick start
Copy the install prompt. Use the green button above this README.
Send it to your agent. Paste it into your coding agent’s chat and send.
Review the setup. Your agent checks the skill’s instructions, requirements, and installation scope.
Migrate PostgreSQL clusters from the Zalando postgres-operator (acid.zalan.do `postgresql` CRs, Spilo/Patroni, WAL-G) to CloudNativePG (CNPG) on Kubernetes, incl. fully air-gapped clusters. Core knowledge: the two walls (Spilo↔CNPG glibc/collation divergence that corrupts physically-copied indexes; WAL-G↔Barman archive incompatibility that strands old backups), three migration paths (logical replication default; initdb.import for small DBs/PG≤13; pg_basebackup as the discouraged same-major exception), the acid.zalan.do→Cluster manifest field map with no-equivalent gaps (preparedDatabases, sidecars, logical-backup cron), backup re-plumbing onto the barman-cloud CNPG-I plugin, HA parity (synchronous + failoverQuorum vs Patroni failsafe), consumer cutover (service/secret renames, scram, cnpg_ metrics), air-gap mirroring, stay-vs-migrate evidence.
