Manage Postgres cluster parameters from the CLI

July 21, 2026

You can now view and update Postgres cluster configuration parameters directly from the pscale CLI, alongside cluster size and replica changes.

pscale branch parameters list <database> <branch> lists every parameter with its current value, default, allowed range, and whether changing it requires a restart. Filter with --namespace (e.g. pgconf, pgbouncer, patroni).
pscale branch resize <database> <branch> --parameters pgconf.max_connections=200 queues a parameter change. The --parameters flag is repeatable and can be combined with --cluster-size and --replicas in a single change request. Add --wait to block until the change completes.
pscale branch resize status <database> <branch> shows the latest change request and its state.
pscale branch resize cancel <database> <branch> cancels a queued change request.

All commands support --format json for scripting and automation.
