Pull request overview

This PR updates PostgreSQL flexible server argument validation to prevent using Premium SSD v2 storage (PremiumV2_LRS) when creating servers on PostgreSQL versions earlier than 14.

Changes:

• Passes version into the storage-type validator.
• Adds a version gate that blocks PremiumV2_LRS creation for PG major versions < 14.

[Copilot]

int(version) is evaluated before pg_version_validator runs (and before any format validation), so invalid inputs like --version foo with --storage-type PremiumV2_LRS will raise an unhandled ValueError instead of a clean CLI validation error. Consider avoiding int() here (e.g., compare against explicit supported majors like ('11','12','13') or safely parse version.split('.')[0] inside a try/except that raises CLIError), or move pg_version_validator(...) earlier so version is validated before this check.

Suggested change

	if version and int(version) < 14:
	raise CLIError('Storage type PremiumV2_LRS is only supported for PostgreSQL version 14 and above.')
	if version:
	try:
	# Accept versions like "14" or "14.x" by using the major component only.
	major_version = int(str(version).split('.')[0])
	except (ValueError, TypeError):
	raise CLIError('Invalid PostgreSQL version "{}".'.format(version))
	if major_version < 14:
	raise CLIError('Storage type PremiumV2_LRS is only supported for PostgreSQL version 14 and above.')

This change introduces new user-facing validation behavior (blocking PremiumV2_LRS for PG < 14) but there’s no test ensuring the create command fails with the expected message for versions 11/12/13. Adding a scenario test case (similar to existing SSDv2 tests) would prevent regressions and ensure the validator is exercised.
