Here is the failure during the following job step:

tools/.github/workflows/package-tests.yml

Lines 34 to 44 in 1e5c046

	- name: generate postgres
	id: generate-postgres
	run: |
	export PROJECT_VERSION="${{ github.event.inputs.project_version }}"
	echo "project_version: ${{ github.event.inputs.project_version }}"
	# To be able to test pipeline without triggering with project_version parameter using workflow_dispatch parameter,
	# if workflow_dispatch parameter is empty, 10.2.1 parameter is set to execute pipeline.
	[ -z ${PROJECT_VERSION} ] && export PROJECT_VERSION=10.2.1
	POSTGRES_VERSIONS=$(python -m packaging_automation.get_postgres_versions --project_version ${PROJECT_VERSION})
	echo "Postgres Version: ${POSTGRES_VERSIONS}"
	echo "::set-output name=pg_versions::${POSTGRES_VERSIONS}"

The failure output:

@gurkanindibay please include information such as the ones above when opening an issue. Make it easier for the readers to understand what is actually going on.

Apparently get_postgres_versions expects the patch version to be an integer, and not something like 0_beta
