Update PostAggregator to be backwards compat (#12138) 

This change mimics what was done in PR #11917 to
fix the incompatibilities produced by #11713. #11917
fixed it with AggregatorFactory by creating default
methods to allow for extensions built against old
jars to still work.  This does the same for PostAggregator
