skip pubviaroot query if postgres version is less than 13

[jgao54]

• Bring back handle out-of-order columns in partitioned table #4035, optionally query for pubviaroot only if pg version >= 13, otherwise default to false since pubviaroot is not supported anyways
• Add e2e coverage to check that a dynamically added partition with out-of-order columns works
• Validate that cdc continue to work on pg 12

Fixes: #3544
