pgEdge Platform

You can use the pgEdge Update Manager module to help manage extensions on pgEdge platform. Command options let you install, remove, upgrade, and check the availability of extensions for your pgEdge installation. To install an extension, use the um install (opens in a new tab) command:

./pgedge um install component_name

Where component_name is the name of the component you wish to install.

You can use the Update Manager list command to find the available build versions and build dates for components that Update Manager can add to your pgEdge cluster; navigate into the pgedge directory, and invoke the command:

./pgedge um list

The Update Manager table displays the following information:

• The Category column identifies the component as a PostgreSQL version, an extension, or an application.
• The Component column lists the name of the component, followed by the PostgreSQL version that the component runs on.
• The Version column displays the available version of the component.
• The ReleaseDt column displays the date that the listed version was released.
• The Stage column displays a note about the build; production releases are noted with the abbreviation prod.
• The Status column displays Installed if the listed component is installed on your system.
• The Updates column identifies components with available updates; you can use the pgedge um update (opens in a new tab) command to update components.
• The PreReqs column identifies any prerequisites required by the component.

PostgreSQL

PostgreSQL (opens in a new tab) is a powerful, open source object-relational database system with over 35 years of active development that has earned it a strong reputation for reliability, feature robustness, and performance.

CLI

pgedge (opens in a new tab) is the name of the CLI for the pgEdge platform.

Spock

The Spock (opens in a new tab) extension provides multi-master (multi-active) replication for PostgreSQL 15 & 16. We leveraged both the pgLogical & BDR2 Open Source projects as a solid foundation to build upon for this enterprise-class extension.

NodeCtl (part of the pgEdge Platform) provides a command-line interface for the Spock extension; for information and to review online documentation, visit the project website (opens in a new tab).

pgEdge Extended Platform

ACE

The ace (opens in a new tab) extension provides the Anti Chaos Engine for a pgEdge SPOCK cluster.

Citus

https://docs.citusdata.com/en/stable/get_started/what_is_citus.html (opens in a new tab)

Citus (opens in a new tab) provides an open source extension that supports PostgreSQL features including distributed tables.

etcd

etcd (opens in a new tab) is a strongly consistent, distributed key-value store that provides a reliable way to store data that needs to be accessed by a distributed system or cluster of machines.

HAProxy

HAProxy (opens in a new tab) is a free, very fast and reliable reverse-proxy offering high availability, load balancing, and proxying for TCP and HTTP-based applications. It is particularly suited for very high traffic web sites and powers a significant portion of the world's most visited ones.

pgBackRest

pgBackRest (opens in a new tab) is a reliable, easy-to-use backup and restore solution that can seamlessly scale up to the largest databases and workloads by utilizing algorithms that are optimized for database-specific requirements.

pgCat2

pgCat2 (opens in a new tab) is a PostgreSQL pooler and proxy (like PgBouncer) with support for sharding, load balancing, failover and mirroring.

pgcurl

pg_curl (opens in a new tab) allows most curl actions, including data transfer with URL syntax via HTTP, HTTPS, FTP, FTPS, GOPHER, TFTP, SCP, SFTP, SMB, TELNET, DICT, LDAP, LDAPS, FILE, IMAP, SMTP, POP3, RTSP and RTMP.

PostGREST

PostgREST is a standalone web server that allows you to access your pgEdge Postgres database cluster with RESTful API calls. It is very simple to use because the API is built on the existing structure and inherits permissions you've already defined in your PostgreSQL database. You use a simple configuration file to specify the schema objects that will be exposed through the API. While the PostgreSQL server monitors the default listener port, for libpq-styled calls to the server, the PostgREST server monitors port 3000 for API-styled calls.

For information about installing and using PostGREST with pgEdge, visit our blog post, pgEdge and PostGREST (opens in a new tab).

ReadOnly

pg_readonly is a PostgreSQL extension that allows you to set all cluster databases to read only.
