Default single-node installation template with extensive configuration parameter descriptions

The meta configuration template is the default Pigsty template. It deploys PostgreSQL on one node, which is the core function of Pigsty.

For compatibility across operating system distributions and architectures, meta installs only the minimum required software.

Overview

  • Config Name: meta
  • Node Count: Single node
  • Description: Default single-node installation template with extensive configuration parameter descriptions and minimum required feature set.
  • OS Distro: el8, el9, el10, d12, d13, u22, u24, u26
  • OS Arch: x86_64, aarch64
  • Related: meta, slim, fat

Usage: This is the default template. You do not need to specify -c meta during configure:

./configure [-i <primary_ip>]

To install PostgreSQL 16 instead of the default version 18, use the -v argument in configure:

./configure -v 16   # or 17, 15, 14; use the pg19 template for PG19 Beta

Explanation

Use meta as the default getting-started configuration for a quick initial deployment.

Use Cases:

  • First-time Pigsty users
  • Quick deployment in development and testing environments
  • Small production environments running on a single machine
  • As a base template for more complex deployments

Key Features:

  • Online installation mode without building local software repository (repo_enabled: false)
  • Default installs PostgreSQL 18 with postgis and pgvector extensions
  • Includes complete observability infrastructure (Grafana, VictoriaMetrics, VictoriaLogs, etc.)
  • Preconfigured Docker and pgAdmin application examples
  • Silo backup storage is disabled by default. Enable it if needed.

Notes:

  • The default passwords are examples. You must change them before production use.
  • Single-node etcd does not provide high availability. It is suitable for development and testing.
  • If you need to build a local software repository, use the rich template
