Overview

PGMQ - Low-level Ruby client for Postgres Message Queue

This is a low-level library providing direct access to PGMQ operations. For higher-level abstractions, job processing, and framework integrations, see pgmq-framework (similar to how rdkafka-ruby relates to Karafka).

Examples:

Basic usage

require 'pgmq'

# Create client with connection parameters
client = PGMQ::Client.new(
  host: 'localhost',
  port: 5432,
  dbname: 'mydb',
  user: 'postgres',
  password: 'postgres'
)

# Or with connection string
client = PGMQ::Client.new('postgres://localhost/mydb')

# Basic queue operations
client.create('orders')
msg_id = client.produce('orders', '{"order_id":123}')
msg = client.read('orders', vt: 30)
client.delete('orders', msg.msg_id)
client.drop_queue('orders')
