pg_later

Execute SQL now and get the results later.

A postgres extension to execute queries asynchronously. Built on pgmq.

Tembo Cloud Try Free

Static Badge PGXN version

Installation

Run with docker

docker run -p 5432:5432 -e POSTGRES_PASSWORD=postgres quay.io/tembo/pglater-pg:latest

If you'd like to build from source, you can follow the instructions in CONTRIBUTING.md.

Using the extension

Initialize the extension's backend:

CREATE EXTENSION pg_later CASCADE;

SELECT pglater.init();

Execute a SQL query now:

select pglater.exec(
  'select * from pg_available_extensions order by name limit 2'
) as job_id;
 job_id 
--------
     1
(1 row)

Come back at some later time, and retrieve the results by providing the job id:

select pglater.fetch_results(1);
 pg_later_results
--------------------
{
  "query": "select * from pg_available_extensions order by name limit 2",
  "job_id": 1,
  "result": [
    {
      "name": "adminpack",
      "comment": "administrative functions for PostgreSQL",
      "default_version": "2.1",
      "installed_version": null
    },
    {
      "name": "amcheck",
      "comment": "functions for verifying relation integrity",
      "default_version": "1.3",
      "installed_version": null
    }
  ],
  "status": "success"
