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

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'

Production pg_partman version --
"name" "default_version" "installed_version" "comment"
"pg_partman" "5.0.0" "5.0.0" "Extension to manage
partitioned tables by time or

DEV Server pg_partman version --
He"pg_partman" "5.0.0" " 4.6.2" "Extension to manage
partitioned tables by time or ID"

Below command PARTMAN EXTENSION new partman.create_parent deployed
SELECT partman.create_parent( p_parent_table => 'test_evt',
p_control => 'test_gts',
p_type => 'native',
p_interval => 'monthly',
p_premake => 12, -- 12 months for future partitions
p_start_partition => date_trunc('month', current_date - interval '36
months')::date::text);

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
