Installing Postgres-related packages v23

Suggest edits

TPA installs a batch of non-Postgres-related packages early during the deployment, then all Postgres-related packages together, and then packages for optional components separately. This page is about installing packages like pglogical that depend on Postgres itself.

To install extra packages that depend on Postgres (e.g., Postgis), list them under extra_postgres_packages in cluster_vars or a particular instance's vars in config.yml:

cluster_vars:
  extra_postgres_packages:
    common:
      - postgres-pkg1
      - postgres-pkg2
    Debian:
      - postgres-deb-pkg1
    RedHat:
      - postgres11-rhpkg1
      - postgres11-rhpkg2
    Ubuntu:
      - ubpkg1

The packages listed under packages.common will be installed on every instance, together with the default list of Postgres packages, and any distribution-specific packages you specify.

There's a separate page about compiling and installing Postgres from source.
