pig install

Install packages through the system’s native package manager and translate PostgreSQL kernel, extension, and common aliases into package names. Use -n/--no-translation when you need to pass raw system package names directly.

pig install pg_duckdb            # install extension and translate package name
pig install pg18                 # install PostgreSQL 18 kernel package group
pig install nginx htop vim       # install multiple system packages
pig install unknown-package -n   # disable translation and use raw package name
pig install pg18 --plan          # preview installation plan
pig install pg_vector -y         # auto-confirm installation

pig sty

Install the Pigsty distribution. See pig sty for details.

pig sty init                     # install Pigsty to ~/pigsty
pig sty boot                     # install Ansible prerequisites
pig sty conf                     # generate configuration
pig sty deploy                   # run deployment playbook
pig sty list                     # list available Pigsty releases
pig sty get 4.5.0                # download a Pigsty release
pig sty grafana list             # manage Grafana dashboards (info/list/boot/load/init/dump/clean/lang/style)

pig inventory

Inspect, edit, validate, check, and exchange the Pigsty inventory (pigsty.yml) with the CMDB. Root-level command group with alias inv; see pig inventory for details. (New in v1.6.0)

pig inventory status             # inspect the active inventory source
pig inventory list               # list inventory topology and value kinds
pig inventory show               # show verbatim inventory YAML (may contain secrets)
pig inventory edit               # edit the inventory (or one fragment) in $EDITOR
pig inventory validate           # validate one complete static Pigsty inventory
pig inventory check              # check inventory, controller, and target readiness
pig inventory diff other.yml     # compare declarations without emitting values
pig inventory cmdb check         # exchange with the PostgreSQL CMDB (experimental)

pig do

Run Pigsty administration tasks through the corresponding Ansible playbooks.

pig pe list                    # list available metric types
pig pe get                     # get all pg_ prefixed metrics
pig pe stat                    # show exporter statistics
pig pe reload                  # reload pg_exporter configuration
pig pe --host 127.0.0.1 -p 9630 get

pig context

Output an environment context snapshot covering host, PostgreSQL, Patroni, pgBackRest, and installed extensions. This command is useful for troubleshooting and for automation scripts that need a quick view of the current node.
