Assistance Needed: Installing Older Version 4.6.2 of Partman Extension on RDS PostgreSQL Production Server

[qazi saif hussain <faiz.qazi0532@xxxxxxxxx>]

Hello,  

I am reaching out regarding an issue we've encountered with the installation of an older version of the Partman extension on our RDS PostgreSQL production server. As you know, we've been experiencing errors with partitioning on our production server, whereas the same script deployed on our development server has been successful. Upon investigation, we discovered that the version of Partman installed on our production server is 5.0.0, while the development server has version 4.6.2 installed.

To address this discrepancy and resolve the partitioning errors on the production server, we need to install the older version of the Partman extension (version 4.6.2) on our RDS PostgreSQL instance.

Action :  Try to create  pg_partman extension  version 4.6.2 getting an error .

CREATE EXTENSION IF NOT EXISTS pg_partman VERSION '4.6.2'  SCHEMA partman;

Error : ERROR:  extension "pg_partman" has no installation script nor update path for version "4.6.2"

Could you please provide guidance or assistance on how we can proceed with installing the older version of the Partman extension on our production server? Specifically, we are looking for steps or best practices to ensure a smooth installation process and avoid any disruptions to our production environment.

When we  PARTMAN EXTENSION    implement on prod noticed  installed_version 5.0.0  But we noticed in Dev server  version 4.6.2 installed 

SELECT * FROM pg_available_extensions where name ='pg_partman'

Error :error msg  ERROR:  Special partition interval values from old pg_partman versions (monthly) are no longer supported. Please use a supported interval time value from core PostgreSQL
